Maximum distance you can reliably first-shot impact 1MOA, 1/2MOA target?

[JustSendit]

MOA is not unreasonable

Personally, I’ve had my best rifle impact miss .1 off the 1in zero target. Sun? Trigger finger? Zero shift? Lot change? I dunno.

I read this as what could I guarantee, I think hitting a 1moa target even at 100, over a long enough period of time, some variable would align and I personally would miss.

Personally 3moa, no problem.

Just my 2c.

What means "over a long enough period of time" to you?
9/10 cold bore shots on different locations?
99/100?
999/1000 maybe?
Specify
Personally 3moa, I consider a problem for 1000/1000.
Bad load, you sneeze while pulling the trigger and so on

fwiw, i'm on day 21 of my experiment. AXSR 300nm @ 410+ yards, 1 shot per day across a holler one ridgetop to another, different times, positions etc. only 2 days rain. None of the misses were from prone or when raining.

17 hits, 4 misses - 81% hit rate
11 of the hits are inside IPSC A zone (1 7/8" tall by 3 7/8" wide box in upper half of the 6"x6" head).
IOW 11 of 21 shots are in a .5 x 1 MOA rectangle. The remaining 6 hits are in 1.5 MOA square.

1 miss was just low and due to ammo (at least, i assume as the garmin read the fps about 5 STD below mean.)
1 miss was just left missed wind call.
2 miss were just high, i attributed one to light and the other to wind moving up the face of the mountain toward the target, but just a guess

I will say, I think i'd have more hits shooting my 6dasher or 6.5x47. 300nm seems a lot less forgiving.

Nice grouping, gunney.

one more update. day 30. had 14 hits in a row until i missed light conditions today and sent it just over top of target.
25 hits, 5 misses - 83% hit rate

day 24 was at a club range and most similar target they had was 2/3 IPSC (4" head) at 465 yards but also -15* angle. still got the hit.

going forward i'm going to mix in some random stuff like thermal clip on, removing and reinstalling barrel on AXSR. need to sort out a better thermal target though as mine is always in shade.

That's pretty neat, that you're actually testing and verifying under real-world conditions.

If I can get this membership at a nicer range I'll be able to test it out myself. Although, last time out, I missed the 1" circle at 100 yards. My mind was .1 mil left. Still turned in a 1/2 (roughly) 5 shot group, but didn't punch that circle.

How it started (.1 mil left) on a 1" circle

How it ended (11/16" circle?)

1/2 moa up to 400 m is requirement put on the weapon and caliber they use. So they train up to 400 m. It's question of percentage how often then can hit 75 mm dia circle at that distance. But in real hostage crisis situations the target is almost always closer than 200 m and , given chance, 75 mm circle are can be hit with confidence. In military, bigger torso size targets are common and training is different

1/2 moa
400m
400m
75mm
200m
75mm.

Why speak in MOA if everything else is in meters?
It sure would make things easier if they used MIL instead of MOA.

Are they afraid of telling people they need to have a first round hit within .15 Mils? (Rounded)
Does it sound too small?


Let's do a 1/4 Mil dot reticle with MOA turrets...
Sounds like Army speak.

75 mm circle regardless of distance. If calculated exactly that's little more than 1/2 moa at 400 m. I prefer to use metric system as well, but people on this forum don't. Now, how did they arrived at 75 mm (that's aprox 3"), I don't know. Might be associated with a critical area on a typical human head...

Probably.
I just find it comical when people mix yards, feet and inches with mm, cm and meters.
I've never had problems wading through it, but it just seems easier/smarter to stick with one or the other. Hence my reference to the Army mil/moa mix optic.

Go into the optic section and you'll see how many times people want to try and define how many inches or moa they missed their target by, when they have a ruler built into their crosshair, and a turret that matches.

The worst offenders with measurements are the British.
