@TheBlackhorse1954 I could be wrong but i believe cowboy action competitions use lever action rifles, many of which are commonly chambered in .30-30. Im not going to knock the 5.56 but the .30-30 is far more lethal. You'd have to intentionally ignore the data not to know that. I dont understand why you keep mentioning competitions but if the targets shot back shooters would probably favor a more lethal round than .223; snipers do.

@lithjimmy

I don't know any snipers who prefer 30-30.

There are so many better alternatives that will allow a sniper to effectively do their job.

Hopefully this will stop all these posts about 30-30's, because they don't have a thing to do with this video or 7.62x39 or 5.56.

If you want to make a video using it, go ahead and do it. If you want to discuss 30-30's, please do it somewhere else.

I don't want to disable comments, but I will if it continues.

Please stay on topic

Mrwiskeytango, 5.56 doesnt stress the gun more. A 5.56 has a slightly different chamber dimension than a 223 chamber. Mine is the 5.56 and will fire either. Thanks.

if teh gun is built for .223 DO NOT FIRE 5.56 ammo out of it. The 5.56 has a higher pressure, somewhere around 60,000 cups, while the .223 is aroun 30,000 cups I believe. The 5.56 stresses the gun more. It can cause damage to the throat, the barrel, the rifling, everything. Just dont do it @utubegeneric

Again, a 5.56 and .223 are different specs. The 5.56 has a thicker case, and a different chamber.

5.56 chamber (and wylde chamber) are larger than .223 and why you can fire 223 out of a 5.56 chamber.

It has nothing to do with stress. The 223 is just too small of a chamber to use the slightly larger 5.56 in it.

@shananagans5 I don't think it was because the 5.45 was more deadly. I think they did it because they changed their war philosophy. Before they're plan was that they would send a swarm of soldiers into battle and all with ak 47s. They have since come to like the accuracy of m16's and therefore went to a cartridge that would offer similar capabilities. The 5.45 is close enough to the accuracy of the 5.56. If the 7.62x39 was more accurate then they would have stuck with it.

@lithjimmy Loading considerations and external, not terminal ballistic performance is why snipers favor calibers other than 5.56, which is extremely lethal (for humans). A 5.56 rifle is a far more effective weapon than a .30-30 for fighting armed men. Google "SDMR".

That's why I never own any rifle smaller than 7.62

[gentrythomas1]

Haha an all the way that's why I love my saiga 7.62 cus its not no .223 piece of shit.

@mojsmg there are probably 10000 in the world that can shoot with in the accuracy of any gun its not the gun its the owner/user

[SNIPERSTEVE420]

why the hell are people arguing about 30-30s??? its a hunting round, the two compared here are miltiary rounds. tottaly diiferent ends of the spectrum. if you plan on going into a combat situation with anything chambered in 30-30, you are an idiot. and 5.56 is weak, jus sayin.

[shananagans5]

@boognish59 You do know at 600 yards the 5.56 still has the energy of a 9mm at close range? Not exactly ineffective. Not to mention, any hit is better than a miss.

[shananagans5]

@lithjimmy It is much easier to get multiple accurate shots off with a 5.56 or .223 than it is with a 30-30. Maybe that's why the military & most police depts use it. Ya think? Not to mention this vid is about 7.62 vs 5.56. Russia even went to a smaller, faster, easier to control round. I wonder if there was a reason for that?

@lithjimmy 223 is a flat fast accurate shooting gun 30 30 drops alot more with more stopping power at 200 yards 223 will be tighter groups that why its more for snipers

[mojsmg]

@63DW89A Really ? You can't even field strip a 336 without tools. So no way you could train a non-shoot to handle that weapon for any long period of time. All you have to do is drop the 336 in sand, drit, mud with the action open(and thats when it'll drop in mid cycle) and that 336 will be done. The 336 takes atleast 10 to 15 mins to break down and clean & thats with a very good gunsmith. The 336 is a great hunting rifle but a bad combat rifle. AR's & AK's smoke 336's in real world combat.
