@wolfpackunr2 Most gun shops have some sort of nato spec ammo. Federal XM195 & XM855 are made at lake city. PMC makes some 5.56 "tactical" ammo... there are lots of brands. If you are not sure if something is NATO spec, then just look at the head stamp on the case. If it is true nato ammo then there will be a circle with a "+" inside; AKA the "nato cross".
@wolfpackunr2 What does your M4 say on the side? If it says 5.56 it can safely shoot both 5.56 & .223. If it only says .223, I'd contact the manufacturer to make sure it's made to also shoot the 5.56. All 5.56s' can shoot .223, but not all .223's can shoot 5.56. The 5.56 is a more powerful version of the 223. Putting a less powerful round in a weapon won't hurt it, however putting a more powerful round in a weapon not made to chamber the more powerful round, is not recommended.
I have a mil spec colt upper on my AR-15 - is that made for the 5.56? what if I shoot .223 in my barrel. What do you think of the WOLF ammo with the lacquer on it - does that wreck my chamber as I heard?
How should I clean it out? much needed great video - Lots of questions on ammo - well done. check out my AR-15 videos. DINODAD32
the steel core 62 grain bullet... doesnt fragment as much because it's designed that way purposefully.. it's main feature is defeating enemy KIT/WEB GEAR/ BODY ARMORE CANTEENS... HELMETS etc... it's not a fragmenting styled round.. it's also used to defeat WOOD.. AND LIGHT METALS and CONCRETE BARRICADES that enemy soldiers might be hiding behind for cover.. that 62 grain steel core penitrator is a good round militarily speaking. and with decent ballistics.
very good video, one of my questions is. i own a Bushmaster AR-15 (A2) style rifle. that totally replicates a military M-16 in look... form... and feel... i'm now wondering if i should fire .223 remington? or 5.56 x 45 NATO only in my rifle.. i need to go look at the marking's and see if it specifies which type of ammo it's chambered for.. this was a very informitive video.. good Ballistic's class.
I have bought only M855 ammo to shoot in my Mini-14 and each of my 2 AR's. Then I reload them.Military brass is heavier than commercial brass cases, so maximum loads should be reduced by at least 10 percent and approached cautiously.
Loved the video. Putting together my AR-15 and trying to match the bullet to the barrel. With the 55gr 556, do you use a 1:9 twist, b/c I am debating between 1:9 and 1:8. Please help.
When it comes to the battlefield..you take care of your rifle before yourself....if your rifle needs cleaning you clean that before you sleep, get chow etc. You don't want the weapon to fail due to being dirty in a fire fight.
long time ago I understood the diferrance thick brass and undersized overal cartrige and the 63000psi for mil spec longer lead in the throat for longer bullets use of millspec brass is ok as long as you reload fired milspec 5.56 and trim to your chamber just do not take milspec 5.56 and put it in .223 chamber with standard chamber lead jambing the long mil pills into the lead will up the copper unit measurment. remember reload that mill brass and reduce all starting loads aneil every 5 loading
dont use 5.56 in a .223 however you can use .223 in a gun chambered for the 5.56. the differences in the 5.56 in a .223 chambered gun could cause damage to the gun and possibly the shooter.
i was looking at buying an ar they have two on buds gunshop one says .223 and one says 5.56x45 o dont know which one to get any suggestions i also was looking at ammo and it said 5.56x45 wat is that exactly and the rifle is a double star any help or input appreciated greatly
I agree with your dimensional difference between the two cartridges of a very small amount, this is to allow for a dirty chamber in battle field use. However I have fired thousands of 5.56 military bulk ammo rounds threw a few .223 chambered rifles, and have had absolutely no problems. Those sammi c.u.p numbers are only an 85 percent number. Modern bolt actions are much stronger than this number, and stronger than a gas operated bolt. Your rifle regulates your prebore , not sammi.
I just looked at my Bushmaster AR 15 and it says .223-5.56 on the side. So does that mean it's a 5.56 that can shoot ,223 rounds? Do all 5.56 say .223-5.56 on them or is it typically one or the other?
I've owned this gun for about 10 years, I don't shoot it much, but I've only purchased 223 rounds for it, I didn't even know there was a difference between the two rounds until just recently.
If you have a rifle chambered in 5.56mm, you can effectively shoot a lower pressure .223rem round without any problems, except for accuracy, and maybe lower pressures that will foul up quicker in the barrel and action. Usually mil-spec ar-15 rifles have barrels that have a rate-of-twist that stabilizes heavier bullets (55 to 86 grain), but would'nt stabilize lighter-weight bullets. The 5.56mm NATO round has a higher pressure to make it a lot more reliable to cycle in mil-spec rifles.
@chromeglock40 There are tons of AR manufacturers out there. Bushmaster, Rock River Arms, and DPMS are some great quality ones, and aren't overpirced. An AR chambered in .223 will be slightly more accurate than a 5.56 chamber, if everything else is the same. There's a wide variety of .223 out there, from 40gr varmint rounds to 90gr for long range benchrest shooting. Whereas 5.56 is limited to 62gr FMJ, which isn't good for hunting, nor target shooting.
@chromeglock40 I'd love to help but I don't know much about AR's in general. I've had mine for about 10 years, and have only shot it once or twice. Planning to put a few hundreds rounds through it this week. I've also purchased a new Tapco stock for it. All the best.
@Vffr1 I tryed to shoot 5.56 in my Masada , ACR whatever you prefer and i had some feeding problems, and then i tryed .223 and it worked fine whats up with that?
@Vffr1 i THINK if says 5.56 mm then you can fire .223 but what ever is says on the side would be what I would put in the rifle, that way you know what it's made for. But yours can fire both.
@Vffr1 My mini-14 says "CAL .223" on the receiver but it is in fact a 5.56 chamber & shoots both .223 and 5.56 like a champ. Just read the manual and contact the manufacturer to know for sure... If your rifle says 5.56 on the side then you will be fine shooting 5.56 and .223.
@Vffr1 Most of them are 5.56... some of the really old non GB models & the new target model are .223 only. I think the ruger site has all the specs; if they don't, you can send them ur serial number & ask... they will get back to you quickly with all the info u could ever need.
Btw the mini-14 was basically designed to be a handy ranch gun / LE rifle, they wanted it to be as versatile as possible & shoot anything you put in it. If you have one of the new non target models it is 5.56.
@CornMakesWhiskey Holy can't believe it Batman! You're right! I have a 182 series Mini 14 (not sure what GB stands for above) but I'm pretty sure that mine can handle 5.56 without issue, which means I can just buy military ammo which I already use for my AR-15, it's cheaper and better (just a bit more powerful). Also I've only shot 200 or less rounds out of my Mini-14 in the past 25 years, but I have started shooting more so it might see 500 rounds this year. Thanks for the great information!!
@Vffr1 Haha glad to help a bro out! GB stands for "government barrel", it has winged front sights, a bayonet lug, thicker barrel, flash hider, the sights are above the bayonet lug, and occasionally the awesome A-team style ruger factory folding stock... they are badass looking! I wish I could afford to buy one of those ruger folding stocks... they are worth more than the gun itself!!!!
@CornMakesWhiskey Okay, I did my homework this time. Ever since then Mini 14's inception, from the first 180 Series built from 1974 - 1977, regular Mini 14s' were produced to shoot both 5.56 and .223. I have an older model Series 182 which was only produced for 1 year, 1981. If my math is correct, it is one of the rarest regular production Mini's produced. Thanks for the great information! Triple
@Vffr1 Nice find! I think that only a few of the older mini-14 models cannot take 5.56; ruger did some funky stuff back then, mixing up parts, changing specs mid production etc... That is why a lot of people knock the mini-14, thankfully ruger got it's act together & the new mini-14s are extremely high quality and consistent (not to knock the older ones, I just noticed that they can be hit or miss).
@NANDO218 such a question shows you have little understanding of firearms.
the most powerful will be whichever has the hotter load, and the most accurate will be the one built with better components and stricter tolerances, while keeping in mind that the weapons chooses its most accurate ammo, not the shooter.
there are infinite combinations of loadings in both calibers, so there is nbo "better" caliber.
that said modern rifles in either caliber are built to be able to safely fire both.
Anyone that thinks they are the same check the accuracy and functioning of a gun made to shoot .223, while firing 5.56 rounds through it. Fire a couple hundred and tell me how your guns holding up. The information provided is one of the most accurate .223 5.56 videos that I have seen online. Thumbs up man.
remember something from/last time I shot a military weapon - they told us to use new 5.56 in the current military rifle. We were told not to use the older 5.56 (close to .223) cause it would jam the barrel. Didn't pay attention to the specifics and tip colors, but think they said one ammo had more punch than the other and we should never use the lesser ammo in the updated rifles. So my guess is that the newer stuff is like +P. Use +P everyday and you'll shorten any life of a handgun. my 2cents.
If your weapon is chambered for 5.56x45,than you can shoot it and .223 from the same weapon. If its .223 chamber than you are supposed to shoot only .233.
People whos say there is no difference between 223 and 556 need to realize there is as much diffence between them as there is between the 308 and 30-06
so let's say i have a golani sporter and use 5.56 NATO rounds in it, my gun would get screwed up? I know that guns that are made for 5.56 NATO can shoot the 223. but my question can there be an exception for a 223 to fire 5.56 depending on the gun?
@mba2ceo In a gun chambered for 5.65 you can shoot both. But in a gun chambered for 223 you shouldnt risk it because in can damage your weapon or you.
I`m not going to argue about this but I`ve been shooting .223, and 5.56 since 1978 interchangably with no trouble so I will continue to do so. But the people who made these calibers so similer, but different (if that is true) was an idiot.
To be honest this 223 vs. 5,56 is just mental-masturbation gun guys do in the same way baseball guys will spend hours talking about stats. Your initial statement is just boilerplate talk from the lawers of SAAMI and the ammo manufacturers. If there is anyone out there who has fired 5.56 in a 223 or vica-versa and has had a catastrophic failure (and I'm not talking about reloaded ammunitionor someone who shot centerfire ammo after firing 22 LR with an adapter) I'd really like to here from you.
@DookieShooter Well, be all means feel free to experiment and come back with your results. We'd love to hear them. For me, all things considered, I'll stick with segregation of those calibers.
I ran the Basic Rifle Marksman qualification range for basic trainees at Fort McClellan, AL for two years and every week I would shoot a can of dented, scratched, damaged, and rounds pushed into the casing compressing the powder charge ( to be honest, this was out of laziness so I would not have to go thru the turn-in process of code+H ammo) with none of them ever causing a problem. So I guess that would qualify as experimenting. On a side note, nothing beats shooting someone elses gun and ammo.
@DocTacDad As you said in other words, to take what you say with criticism. I am going to point out I dont believe they leave the annealing carbon residue on so that they can verify that it has been annealed, but as to take one step out of the assembly line such as polishing cartridges, because ultimatly they want mass produced ammunition that brings the boys home, and with civilian ammunition they like it to look nice so that it is more appealing to the consumer so they polish it.
@DookieShooter in my bushmaster the highly advise you to use a remington .223 for a good reason i was using cheap rounds 5.56 nato and they produce way more pressure and carbon build up in your chamber and gas tube than a .223 so what happened was due to the added pressure my gas tube and gas key bacame lodged into eachother forcing me to buy a new gas tube and key. also the pressure can crack your reciever, i also seen higher pressure rounds blow barrels.i use propper rounds now from experience
I can run both in my Min-14 and there is a differance.. I found out when sighting in at 100 yards and loaded in a few 5.56 rounds and it changed everthing.. I thought I broke something.. lol Check your manual is all I can say.
@mrrottenjuggalo check your facts before you get someone hurt. They press bullets to certain tolerances for a reason just cause it won't fit doesn't mean you go to your rock chunker and make it fit . Dumb ass
dont belive the bulshit you hear on the internet about this topic. firing these rounds in a bolt action you will be fine! if you have problems closing the bolt with 5.56 than put em on your press and seat them a little deeper, problem solved. in a semi auto the only problem you will have is that the older M16 clones don't like the higher pressures and take a pounding due to faster gas port cycle. this is the #1 reason for the .223/5.56 NATO warning. nothing else. eather way you wont blow up!
They should just make all chambers 5.56. It was dumb in the first place to make two different cartridges. You probably won't squeeze out that much more accuracy with a .223.
Yeah...I have different .223s and case neck length and width are always slightly different between brands, and weights. Not to mention bullet length, and width.
Reminds me of 240 Volts versus 480 Volts. They are both electrical voltage and can both hurt you but one is much different in charicteristics than the other.
I was in the Army and I have owned an AR 15 since 1978 I have never had any trouble shooting either .223 or 5,56 out of it. Other then the difference between military grade vs commercial grade ammo, if anyone has any issues they should consult the manufactureer of the firearm.
everyone just DO YOURSELF A FAVOR and buy a 5.56 rifle and then u can shoot either or and u dont have to worry about watching these RETARDED VIDEOS.......
the US military DOES NOT and HAS NOT used the 55gr M193 round since the 62gr M855 round was invented.. to claim that it is standard issue is wrong. The M193 is cheaper for a reason; it is inferior to M855 (IN EVERY ASPECT) or else the military would have stayed with M193. M193 was NOT designed for fragmentation but does occassionally as you stated. However, M855 will do this as well sometimes, but will more often tumble instead.. I've seen what it does to insurgents :) Has anyone else here? nope
this is hilarious no on knows what there talking about and just continue to act like they do ... funny stuff. 5.56 and 223 are not the same 5.56 will create higher pressures plus a difference in velocity ft/sec as well
so essentially, 5.56mm is made with thicker brass and loaded hotter resulting in a greater chamber pressure making it unsafe when used in a rifle that is chambered in .223?
and... ummm... then... aaahh.. when you look at the .... ummm, pressures.... ummm... - - -Just messing with you man. i have often been involved in debates about this and you helped. Nicely done! I appreciate the info. Thanks for doing your homework. Much respect. saved me a bunch time starting my own research and gave me a baseline to go off of. Appreciate this video.
@MichaelRoxalot if your AR-15 says it shoots both your good to go. even if it only says it can use the 5.56mm you're still good to use both. the main issue is using the 5.56 round in a gun made to shoot the .223 rem. the difference in pressure can damage the gun and the very slight diference in the casing can also cause issues.
Cartridge external dimensions are exactly the same they have to be
The CIP test pressure limits are Identical for both SAAMI are lower to take into account all rifles in all condition. If this were not "True& Correct "5.56 would have to be listed as a different cartridge & totally banned in .223 Remington rifles. The 0.3 grain weight difference would be ahead of the rim to strengthen it for use in MINIMI (MG 243) Always watch presure signs when handloading
@TheTabellarius Wiki warns a 5.56 in a .223 barrel is extremely dangerous
Test barrels made for 5.56mm NATO measure chamber pressure at the case mouth, as opposed to the SAAMI location. This difference accounts for upwards of 20,000+ psi difference in pressure measurements. That means that advertised pressure of 58,000 psi for 5.56mm NATO, is around 78,000 psi tested in .223 Rem test barrels (SAAMI .223 Rem Proof MAP is 78,500 psi so every 5.56mm round fired is a proof load, very dangerous).
@TheTabellarius DO NOT shoot 5.56 in a .223 rifle unless your owners manual for the rifle specifically states that it will not cause a problem. You CAN however shoot .223 in 5.56 marked rifles(although there may be a few exceptions). Shooting 5.56 in a .223 rifle can cause CATASTROPHIC failures including but not limited to loss of fingers. Just an FYI, anyone can post "facts" on wikipedia.
@TheTabellarius Did you watch the video? Ok, let me break this down for you the external dimensions of the two are virtually the same. The internal dimensions are different. The THICKER brass of the 5.56x45NATO will cause an increase in pressure, due to less volume for gases to expand, and the longer LEADE length will dramatically increase the pressures if shot in a .223 Rem chamber due to tighter tolerances in that chamber; which can make it dangerous to do so. BTW - NATO rounds are not SSAMI
@TheTabellarius The NATO rounds have not changed they have always been higher pressured, it is dangerous if the chamber is not compatible with it. SSAMI doesn't regulate NATO or Military rounds. They do however tell you not to shoot 5.56x45NATO in the .223 Rem chamber.
@TheTabellarius sorry thetabellarius, your wrong, you should change your name to theterrible because its too obvious that you cannot collect correct info. they are differences between .223 and 5.56, this is why all gun manufactures do not recommend shooting 5.56 in a rifle chamber for .223. this will void your warranty on the rifle. i think that these manufactures know a little more than you or I about these chamber pressures and that is why the give you these cautions,
.223 / 5.56 are the same thing unless the Military has taken to a new loading I don't know of pressures should be the same. It is the same case. Overpressure will cause massive problems including blow up of the action. Ruger M77 has what is known as a Military "extended throat" designed to handle the odd bad bullet seating. I thought it would afect my handloads it does not I can get 3/8" groups at 100m 110 yds
@TheTabellarius The .223 Rem and the 5.56x45 NATO are NOT the same case. The 5.56 has thicker brass and is loaded to higher pressures. The chambers on the .223 Rem are also tighter. If you don't believe me call up Federal or Winchester and ask them, but don't make the mistake of shooting whatever just because they appear the same; they simple are not.
my panther arms is marked 1.9- 5.56 nato on the barrel its self ! ive been shooting 223. only since purchased...would this be a option for me as defense ammunition (5.56) seeing as the barrel is marked for it? it is a dpms ar low profile classic (optics only) thanks in advance
@youWILLlose2012 The beauty of having a 5.56 chamber is you can shoot both 5.56 & .223...there are many great options out there for self defense rounds. The Hornady TAP ammo comes to mind as well as A-Max or V-Max rounds. Both 5.56x45 NATO and .223 Rem are suitable for self defense.
@sonofthesun2188 What matters more than weight is the actual length of the bullet. I'd say you'd be hard pressed to find a 75gr round that is short enough to stabilize in a 1:9. A standard lead core 60gr round should be fine in the 1:9. The military m855 62gr is steel core and so it tends to be a longer bullet for it's weight class.
@sonofthesun2188 One thing you need to be aware of is the OAL (overall length of the round) that can cause over pressure if the bullet is jammed up against the rifling when chambering. This usually only a problem in the 80 gr range. If the barrel twist is not fast enough you won't get enough stability on the round and it will be inaccurate.
Ive heard from one or two local gun shops say that its a bad idea to use the steal core ammo. Says it wears out the riflings very rapidly. Anyone know if this is true or not?
@RenmarStriff That's the first I've heard of it. I don't think it makes a difference. The steel core is shrouded by a copper jacket that will deform in the rifling, and many of the steel core ammo still has lead mixed in, or around the core. Now if you were shooting a pure steel bullet I'd see how that would do damage. They weren't talking about steel cased ammo where they?
@DocTacDad No I asked that specificly. I am still a newbie when it comes to these AR's and there ammo. Coupled with my barrle is chrom lined I wanted to make sure before I shot anymore of that stuff through it. I wouldnt doubt if there wrong though sence this guy is pretty much a little back woods store owner and know it all complex. He does sell his guns cheap though XD
@RenmarStriff Well, I'll put it to you this way the military runs millions of steel core rounds through their rifles every year...if the stuff was bad they would have dropped it by now. Hope that helps. ~Doc
@RenmarStriff That is not true. a jacketed bullet is lead surrounded by a copper jacket. the steal core ammo you speak of is simple a lead bullet with a steal penatrator that is wrapped with the same copper jacket. it will not harm your barrel nor will it wear it out any faster.
@Jayho74 Umm...Lets see...If you load the same bullet in a 5.56 and a 223. the 5.56 will have a higher muzzle velocity then the .223 so yes it will go faster longer. If you load a bullet with high drag coefficient, sectional density in the .223 it might overtake it further out....does that answer you question? The practical difference can be great when talking FMJ (full metal jackets), because of the particular construction of the m193 ball. It has a high probability of fragmentation in flesh.
I have been lazily researching this topic for the past four months and you just finished all the questions i had a hard time finding the answers for. Thank you!!!
Although I understand there are technical differences between the two rounds , everyone I know personally uses them interchangeably and some have for many years without problems. I'm not saying this is safe, just that I have yet to see problems by doing this.
@dragonballjiujitsu I know ppl that have done that as well...but you never know if you are stressing the metallurgy in the chamber too far...I say better safe then sorry. Thanks for watching and comment!
So I am going with 223 hallow points in my rifle. All I care about is digging huge holes in bad guys.

dont use 5.56 in a .223 however you can use .223 in a gun chambered for the 5.56. the differences in the 5.56 in a .223 chambered gun could cause damage to the gun and possibly the shooter.

If you have a rifle chambered in 5.56mm, you can effectively shoot a lower pressure .223rem round without any problems, except for accuracy, and maybe lower pressures that will foul up quicker in the barrel and action. Usually mil-spec ar-15 rifles have barrels that have a rate-of-twist that stabilizes heavier bullets (55 to 86 grain), but would'nt stabilize lighter-weight bullets. The 5.56mm NATO round has a higher pressure to make it a lot more reliable to cycle in mil-spec rifles.

chromeglock40 1 month ago
@chromeglock40 There are tons of AR manufacturers out there. Bushmaster, Rock River Arms, and DPMS are some great quality ones, and aren't overpirced. An AR chambered in .223 will be slightly more accurate than a 5.56 chamber, if everything else is the same. There's a wide variety of .223 out there, from 40gr varmint rounds to 90gr for long range benchrest shooting. Whereas 5.56 is limited to 62gr FMJ, which isn't good for hunting, nor target shooting.

@Vffr1 i THINK if says 5.56 mm then you can fire .223 but what ever is says on the side would be what I would put in the rifle, that way you know what it's made for. But yours can fire both.

@Vffr1 My mini-14 says "CAL .223" on the receiver but it is in fact a 5.56 chamber & shoots both .223 and 5.56 like a champ. Just read the manual and contact the manufacturer to know for sure... If your rifle says 5.56 on the side then you will be fine shooting 5.56 and .223.

@Vffr1 Most of them are 5.56... some of the really old non GB models & the new target model are .223 only. I think the ruger site has all the specs; if they don't, you can send them ur serial number & ask... they will get back to you quickly with all the info u could ever need.
Btw the mini-14 was basically designed to be a handy ranch gun / LE rifle, they wanted it to be as versatile as possible & shoot anything you put in it. If you have one of the new non target models it is 5.56.

@CornMakesWhiskey Holy can't believe it Batman! You're right! I have a 182 series Mini 14 (not sure what GB stands for above) but I'm pretty sure that mine can handle 5.56 without issue, which means I can just buy military ammo which I already use for my AR-15, it's cheaper and better (just a bit more powerful). Also I've only shot 200 or less rounds out of my Mini-14 in the past 25 years, but I have started shooting more so it might see 500 rounds this year. Thanks for the great information!!

I wish I could afford to buy one of those ruger folding stocks... they are worth more than the gun itself!!!!

@CornMakesWhiskey Okay, I did my homework this time. Ever since then Mini 14's inception, from the first 180 Series built from 1974 - 1977, regular Mini 14s' were produced to shoot both 5.56 and .223. I have an older model Series 182 which was only produced for 1 year, 1981. If my math is correct, it is one of the rarest regular production Mini's produced. Thanks for the great information! Triple

@Vffr1 Nice find! I think that only a few of the older mini-14 models cannot take 5.56; ruger did some funky stuff back then, mixing up parts, changing specs mid production etc... That is why a lot of people knock the mini-14, thankfully ruger got it's act together & the new mini-14s are extremely high quality and consistent (not to knock the older ones, I just noticed that they can be hit or miss).

NANDO218 1 month ago
@NANDO218 such a question shows you have little understanding of firearms.
the most powerful will be whichever has the hotter load, and the most accurate will be the one built with better components and stricter tolerances, while keeping in mind that the weapons chooses its most accurate ammo, not the shooter.
there are infinite combinations of loadings in both calibers, so there is nbo "better" caliber.
that said modern rifles in either caliber are built to be able to safely fire both.

remember something from/last time I shot a military weapon - they told us to use new 5.56 in the current military rifle. We were told not to use the older 5.56 (close to .223) cause it would jam the barrel. Didn't pay attention to the specifics and tip colors, but think they said one ammo had more punch than the other and we should never use the lesser ammo in the updated rifles. So my guess is that the newer stuff is like +P. Use +P everyday and you'll shorten any life of a handgun. my 2cents.

To be honest this 223 vs. 5,56 is just mental-masturbation gun guys do in the same way baseball guys will spend hours talking about stats. Your initial statement is just boilerplate talk from the lawers of SAAMI and the ammo manufacturers. If there is anyone out there who has fired 5.56 in a 223 or vica-versa and has had a catastrophic failure (and I'm not talking about reloaded ammunitionor someone who shot centerfire ammo after firing 22 LR with an adapter) I'd really like to here from you.

I ran the Basic Rifle Marksman qualification range for basic trainees at Fort McClellan, AL for two years and every week I would shoot a can of dented, scratched, damaged, and rounds pushed into the casing compressing the powder charge ( to be honest, this was out of laziness so I would not have to go thru the turn-in process of code+H ammo) with none of them ever causing a problem. So I guess that would qualify as experimenting. On a side note, nothing beats shooting someone elses gun and ammo.

@DookieShooter in my bushmaster the highly advise you to use a remington .223 for a good reason i was using cheap rounds 5.56 nato and they produce way more pressure and carbon build up in your chamber and gas tube than a .223 so what happened was due to the added pressure my gas tube and gas key bacame lodged into eachother forcing me to buy a new gas tube and key. also the pressure can crack your reciever, i also seen higher pressure rounds blow barrels.i use propper rounds now from experience

Military primers have thicker brass in their strike surface in order to function
in semi and full auto weapons without discharging while cycling rounds.
I would not recommend the use of commercial .223 ammo in any semi
or full auto weapon due to their thinner primer strike surface and the possibility
of a discharge due to the firing pin inadvertently striking the primer or the
bullet of another round inadvertently striking the primer.

the US military DOES NOT and HAS NOT used the 55gr M193 round since the 62gr M855 round was invented.. to claim that it is standard issue is wrong. The M193 is cheaper for a reason; it is inferior to M855 (IN EVERY ASPECT) or else the military would have stayed with M193. M193 was NOT designed for fragmentation but does occassionally as you stated. However, M855 will do this as well sometimes, but will more often tumble instead..

@jalbertsonjr how can you say there is a difference in velocity between the two calibers?
muzzle velocity depends on barrel length, powder charge & bullet weight. it does NOT depend on what markings there are on the brass.
the rule is: weapons chambered in 5.56 can shoot .223
weapons chambered in .223 can also shoot 5.56, but contact manufacturer to make sure it wont get damaged in the long run.
in NO case will a 223 ar "kaboom" just because you fed it 1 round of 5.56 for fucks sake.

Did a quick check Wiki 5.56 & .223
Cartridge external dimensions are exactly the same they have to be
The CIP test pressure limits are Identical for both SAAMI are lower to take into account all rifles in all condition. If this were not "True& Correct "5.56 would have to be listed as a different cartridge & totally banned in .223 Remington rifles. The 0.3 grain weight difference would be ahead of the rim to strengthen it for use in MINIMI (MG 243) Always watch presure signs when handloading

@TheTabellarius Ok, ok lets just agree to disagree.
DocTacDad 9 months ago
@TheTabellarius Wiki warns a 5.56 in a .223 barrel is extremely dangerous
Test barrels made for 5.56mm NATO measure chamber pressure at the case mouth, as opposed to the SAAMI location. This difference accounts for upwards of 20,000+ psi difference in pressure measurements. That means that advertised pressure of 58,000 psi for 5.56mm NATO, is around 78,000 psi tested in .223 Rem test barrels (SAAMI .223 Rem Proof MAP is 78,500 psi so every 5.56mm round fired is a proof load, very dangerous).
seanzoz 7 months ago
@TheTabellarius DO NOT shoot 5.56 in a .223 rifle unless your owners manual for the rifle specifically states that it will not cause a problem. You CAN however shoot .223 in 5.56 marked rifles(although there may be a few exceptions). Shooting 5.56 in a .223 rifle can cause CATASTROPHIC failures including but not limited to loss of fingers. Just an FYI, anyone can post "facts" on wikipedia.

Thicker walls mean less powder space.
These cartridges have SSAMI set dimensions & pressures unless the US
military has made drastic changes to the M16 or had extraction problems
none seen during my service did see failure to extract causing fresh
round ignite primer and blow upper receiver out. I see no reason for thicker brass
Surplus ammo is available for sport shooter,
doubt they would risk of higher chamber pressures blowing up a
sport rifle your claim a little hard to swallow
TheTabellarius 9 months ago
@TheTabellarius Did you watch the video? Ok, let me break this down for you the external dimensions of the two are virtually the same. The internal dimensions are different. The THICKER brass of the 5.56x45NATO will cause an increase in pressure, due to less volume for gases to expand, and the longer LEADE length will dramatically increase the pressures if shot in a .223 Rem chamber due to tighter tolerances in that chamber; which can make it dangerous to do so. BTW - NATO rounds are not SSAMI
DocTacDad 9 months ago
@TheTabellarius The NATO rounds have not changed they have always been higher pressured, it is dangerous if the chamber is not compatible with it. SSAMI doesn't regulate NATO or Military rounds. They do however tell you not to shoot 5.56x45NATO in the .223 Rem chamber.
DocTacDad 9 months ago
@TheTabellarius sorry thetabellarius, your wrong, you should change your name to theterrible because its too obvious that you cannot collect correct info. they are differences between .223 and 5.56, this is why all gun manufactures do not recommend shooting 5.56 in a rifle chamber for .223. this will void your warranty on the rifle. i think that these manufactures know a little more than you or I about these chamber pressures and that is why the give you these cautions,
ghostar15man 8 months ago
.223 / 5.56 are the same thing unless the Military has taken to a new loading I don't know of pressures should be the same. It is the same case. Overpressure will cause massive problems including blow up of the action. Ruger M77 has what is known as a Military "extended throat" designed to handle the odd bad bullet seating. I thought it would afect my handloads it does not I can get 3/8" groups at 100m 110 yds
TheTabellarius 9 months ago
@TheTabellarius The .223 Rem and the 5.56x45 NATO are NOT the same case. The 5.56 has thicker brass and is loaded to higher pressures. The chambers on the .223 Rem are also tighter. If you don't believe me call up Federal or Winchester and ask them, but don't make the mistake of shooting whatever just because they appear the same; they simple are not.

So in short... you can shoot the 223 out of a 5.56 but not the other way around due to pressures. Took 30 seconds to say that.

sonofthesun2188 9 months ago
@sonofthesun2188 What matters more than weight is the actual length of the bullet. I'd say you'd be hard pressed to find a 75gr round that is short enough to stabilize in a 1:9. A standard lead core 60gr round should be fine in the 1:9. The military m855 62gr is steel core and so it tends to be a longer bullet for it's weight class.
DocTacDad 9 months ago
@DocTacDad so it will just be inaccurate or/and mess my barrel up?
sonofthesun2188 9 months ago
@sonofthesun2188 One thing you need to be aware of is the OAL (overall length of the round) that can cause over pressure if the bullet is jammed up against the rifling when chambering. This usually only a problem in the 80 gr range. If the barrel twist is not fast enough you won't get enough stability on the round and it will be inaccurate.
DocTacDad 9 months ago
@DocTacDad cool thanks you helped me a lot.
sonofthesun2188 9 months ago
@DocTacDad so this is what i got so far,

@RenmarStriff That's the first I've heard of it. I don't think it makes a difference. The steel core is shrouded by a copper jacket that will deform in the rifling, and many of the steel core ammo still has lead mixed in, or around the core. Now if you were shooting a pure steel bullet I'd see how that would do damage. They weren't talking about steel cased ammo where they?

@RenmarStriff That is not true. a jacketed bullet is lead surrounded by a copper jacket. the steal core ammo you speak of is simple a lead bullet with a steal penatrator that is wrapped with the same copper jacket. it will not harm your barrel nor will it wear it out any faster.

@Jayho74 Umm...Lets see...If you load the same bullet in a 5.56 and a 223. the 5.56 will have a higher muzzle velocity then the .223 so yes it will go faster longer. If you load a bullet with high drag coefficient, sectional density in the .223 it might overtake it further out....does that answer you question? The practical difference can be great when talking FMJ (full metal jackets), because of the particular construction of the m193 ball. It has a high probability of fragmentation in flesh.

Buy a 5.56 and use .223 in it if you feel so inclined, that is all I need to know...lol

@jimkressin Yes, the Wylde chamber is good to go on both the .223 and 5.56. Thanks for watching and commenting!

Although I understand there are technical differences between the two rounds , everyone I know personally uses them interchangeably and some have for many years without problems. I'm not saying this is safe, just that I have yet to see problems by doing this.

@dragonballjiujitsu I know ppl that have done that as well...but you never know if you are stressing the metallurgy in the chamber too far...I say better safe then sorry. Thanks for watching and comment!
