MOA or Minute Of Angle

[AutoCrete]

@59LOWLIFE The best ammo for any rifle is a hand loaded round specifically developed for that individual rifle. That same round has a great probability of not working as good in the same make and model of rifle with a serial number one higher or one lower than the rifle the round is made for.

Rifles are like fingerprints, very individual. The best ammo for any given rifle is developed for that individual rifle.

[jdmSRT]

Sorry if this question sounds dumb but if someone says that their AR-15 shoots 1 MOA at 100 yards mean their grouping on the paper target would all be within 1"? And if so would that mean their grouping at 200 yards would be all within 2"s?

Lastly if a scope is at zero and you shoot it at let's say 100 yards and you shot say two inches lower than what you intended and the elevation knob says that if you turn the knob clockwise for up to adjust 1/8 per click does that mean I turn it clockwis

[BeyondNeptune]

technically, if you're following a circle, the distance you are talking about is the arc length, not the vertical length. But at tiny angles, it doesn't matter too much.

[nupeswv]

I must also add that 90% of the rifle scopes out there do not clik fractional amounts of MOA as they claim. The measurement is actually IPHY which stands for 'inch per hundred yards". They are close to each other but if one were to hold over a 20 MOA instead of IPHY, a miss of 10" can occur at longer distances

[nupeswv]

Actually MOA is "minute of angle" only for country bumpkins. "MOA" actually is "minute of arc" for scientific people and other folks who want to be exact.

Semantics aside, the correct definition for it is relavent in this case because the definitive terms underlying it are related to "arc" specifically as a prefix...arcsecond, arcminute ect.

Why do people teaching things begin on an foundation of teminological error?

[fallout114]

I get it. Thank you :D



[3n16m4666]

sir, you explained MOA so much better than anyone else on youtube.

[General734]

im sorry, but it wasnt easy to follow, and i couldent see what u had written, so if 1 moa = 1 inch at 100 yards, does that eaquil 2 inches at 200 yards? sorry for my bad english, im from norway wich makes another problem... i have to convert to the metric system :/

[ClearlyFish]

@General734 Please check out my MOA part 2 video. It may be more useful for you. thanks

[cpratt1976]

@General734 Yes. One moa at 100 yards is 1 inch. One moa at 200 yards is 2 inches and so on. Technically one moa at 100 yards is 1.047 inches or one moa at 91.44 meters equals 2.7 centimeters.

[59LOWLIFE]

What is the best type of ammo for a rifle?

[phoenix1916]

I always knew the basic rule that 1 moa @ 100 yds, 2 moa @ 200 yds and so fourth, never knew how it was achieved, thankyou for this informative video!

[MahouBlanc]

UPS guy hahaha good one!!

[TheRealTrojanGoat]

Excellent explanation, but jeez, I only wanted to know how to hit stuff

[WideEyedPride]

so if you were to make 8 clicks to the right on that scope you have, the round would land one inch to the right of where the scope is aiming? (assuming that no other factors like wind effected the shot?)

[ClearlyFish]

@WideEyedPride That's correct. One inch to the right at 100 yards. That adjustment actually moves the crosshairs to the left. so it can be a bit confusing but a right adjustment moves the muzzle/round to the right.

[SwiftSilentDedly0321]

I have a question, when a rifle is zeroed the only reason a 2MOA grouping could occur is because of the shooters imperfection correct?

[ClearlyFish]

@SwiftSilentDedly0321 Other factors do come into play. The quality of your ammunition can make a big difference. If you're using cheap mass-produced ammo, don't plan on getting any tighter. Also, the quality of your rifle and wind come into play. And yes, Shooter's error is a big one.

[jularias57]

Thank you Sir for the answer. The new generation of american soldiers we have in today's Armed Forces are very smart (computers, new gadgets, technology, etc). Also a lot of smart **&^, who asks a lot of questions (LOL). Thanks again.

[jularias57]

Good video, it has helped me to better explained MOA to my soldiers. A question, why MOA is based on a CIRCLE or circunference?

Why it is not based on a square like a target paper?

[ClearlyFish]

@jularias57 Happy to help out Soldiers. I have a few active duty in the family.

I suppose the question would be why is it an angular measurement rather than a linear measurement. If you were to calibrate your turrets of a rifle scope to a linear measurement like inches, They would be accurate at, say, 100 yards but you'd still have to convert at other distances. By using an angular measurement like MOA or Mil-Dot, it provides an accurate description regardless of the distance to the target.

[M14EBRMadman]

So, 1 MOA at 200 yards = 2inch and 2 MOA at 200 yards = 4 inch?

[ClearlyFish]

@M14EBRMadman That's correct.

[M14EBRMadman]

@ClearlyFish Thank you, i was also wondering if Remix350 was right with his question.

[ClearlyFish]

@M14EBRMadman I produced a follow up video that goes into more detail (MOA or Minute of Angle Part II) Or try this formula: No. Clicks = (8 * drop *100)/D where: 8 is the click value; D is the distance to the target; and drop is the bullet drop at that distance. That yields 8 clicks per inch at 100 yards; 4 clicks per inch at 200 yards, 2.7 (3) clicks per inch at 300 yards; 2 clicks per inch at 400 yards; etc.

[Remix350]

So If A Scope is1/8 MOA Like The One You Have, Do You click it 8 times for a 100m drop?

[ClearlyFish]

@Remix350 Check out my MOA part II vid. It may answer some of your questions.

[M14EBRMadman]

@Remix350 I was wondering the same as you asked. Have you figured out yet? Please let me know :D

[GscottS16]

@ClearlyFish so you need to know the bullet drop to know how many clicks to do/how many MOA the target is?

[mysticookiebear]

Thank you Master Gordon

[ajoverson]

hey your video was helpful but what most of us out in the real world is how to effectifly use the MOA on our rifle scopes!!! like if my scope is 0ed at 200 yards how do i calculate a chart on how many MOA i need for targets from 25-1000 yards

[ClearlyFish]

@ajoverson I finally put together a video shows how to calculate your chart. Check out "MOA or Minute of Angle Part II".

[Fallout3Follower]

All of these factors that come into play is what makes Snipers such as Carlos Hatchcock living legends.

[kevo1264]

Is there a video anywhere describing how to use elevations knobs and wind age knobs for compensation with bullet drop. This is all basically math, which i was never good at.

[ClearlyFish]

@kevo1264 That's on my to-do list that I hope to get accomplished sometime over the next decade. Bullet drop is easiest to figure. You'll need a ballistic chart for whatever caliber/load you're shooting. Look up the trajectory at your target distance, typically given in inches. Adjust your scope based on the click value. For example, .223 WSSM at 300 yards has a trajectory of -4.9. If your click value is 1/4 MOA then multiply 4 times -4.9 to get 19 clicks to center.

[ClearlyFish]

@kevo1264 Wind drift is similar to bullet drop but more tricky to calculate and too complicated to explain here. Hopefully, I have time to get around to a video.

[1967spud]

@kevo1264 i am now working on one which should be finished and published b ythe weekend

you will be able to find it on my channel at 1967spud thanks

[1LonePuma]

Very interesting; however, couldn't see with the type of pen used or quality of camera.  Other wise, good to listen to.

[AR15forNoobs]

Awesome video, thank you!

[Larrye123]

Hi, would you go with a scope with 1/4" turrets or 1/10th MIL turrets? The range I will be shooting at is 300 yards max. I'm interested to know which turret is more precise if you know. Thank you!

[ClearlyFish]

@Larrye123

HI. Thanks to all for the feedback.

One mil is 3.6 inches at 100 yards. So 1/10 mil would be 0.36 inches or a hair more than 1/3 of an inch. 1/4 MOA is 0.25 inches. That makes the 1/4 MOA more precise than 1/10 mil.

[sn012]

good explanation sir 10/10

[lenthesniper]

i got a bit lost to begn with but i understood it at the end, interesting video.

[headphones222]

The best attempt at mathematical explanation of MOA I have ever seen.

And by far the most correct one!!!!!!

Kepp it up dude.

[lildude52ca]

That was a good explanation of what it is, but how about how showing how its used and what to do with it, ( for the new people of course )

[BatDog69]

Thanks!

[bmetstud]

holy crap! 5 STARS. how about calculating for wind??? thanks great video. Always wondered how they got that.

[netstepb]

That was a poor explanation guy.
