Same idea, and you already have a measuring device on your rifle, or SHOULD. Ten mils is 36" at 100 yards.
The 100 yard elevation zero is made up of two parts: Compensation for bullet drop from muzzle to 100 yards; and the mechanical offset of the line of sight over the line of bore. With a .308 the bullet drop is about 2.7 inches. Assuming a sight height of 1 3/4 inches, at 100 yards that's about 1.7 MOA. Add them up: 4.3 MOA.
NW Colorado. Apr 5, 2020. #24. To the OP, think about it in simple terms. Zero at 100-yards or 100-meters (~109-yards), it really doesn't matter for most CF rifle cartridges as it won't make a difference. The drop at 100 +/- 9-yards is a very small insignificant amount, which is not noticable.
Out to 100 from a close pistol target. You're making me 2nd guess it now... will have to verify. I'm zeroed with cci SV (and its pretty close with other similar rounds, such as sk std+ etc) at 50 yards. I'm certain at 75 its .9 and at 100 its 2.1. Thought I might be going crazy for a second and checked my dope lol.
I zero at 200 for two reasons: 1. I use this rifle for LR DMR type copmetitions and it works out better for holdovers with my rifle/load/reticle. 2. I have acess to a 200yard range. IIRC I'm only 1.7-1.9in high at 100yds which isn't too much of an issue for me to compensate for at 100yds. YMMV.
Dec 13, 2008. 402. 17. San Ramon, CA. Aug 17, 2009. #1. I would like to know just how accurate an AR15 can be, at short ranges, such as 100 and 200 yards, using a bag or bi-pod. Assume the rifle is built using high quality parts best suited for this kind of shooting and either Lapua or hand loaded ammo optimized for the gun.
Re: MOA at 100 yards is it possible with a 22lr? There are several LOW quality .22LR rifles that can shoot MOA out to 100 yards, real competition .22 rifles can do much better. I've seen several low budget combinations make it, cheapest one I know of is a Norinco JW-15 with BSA 36x scope in Leapers 1-piece rings/base shooting Wolf Extra.
If your scope is IPHY adjustments- there is a quick equation. Distance/100 * adjustment value = total inches of adjustment at given distance. Example- 530 yards, Scope with 1/4 adjustments. 5.3 * 1/4 = 1.325" @ 530 yards. 875 yards, Scope with 1/4 adjustments.
I shot exactly one NRL match with it and it came right back off and I went back to my Viper Gen II. It parallaxes well at 75 yards, but at 50 I started to struggle. We had a KYL at 30 yards, and I was really guessing where the .5 and .25 targets were.. For the KLY I was running about 12 power, and the Viper I use is a 3-15, its rarely maxed out.
So a 70 yard gravity zero would have an expected drop .4 MOA LESS than the 100 yard zero at 200 or a predicted 200 yard comeup of .6MOA. Same goes for SOB the taller the delta the less adjusted drop at 200. A 3.5” as the op stated vrs a normal AR height of 2.5” would result in a .5 moa 200 yard prediction.
