The reason I bought my rifle was primarily hobby. I intend to target shoot at ranges most. Dunno if competition is in the future or not. Maybe. I zeroed to 25 yards only because that was the farthest position at the indoor range I was at. I would've done a 50 yard zero if I could have.
cbickel,
What type of setup are you running? Optics or iron sights?
I start at 50yds and dial in there, then at 100yds Im about 4-5 in high with .223 AR then adjust from there... I like to have my AR shoot 1.5 inchs high at 100yds... But thats just me, everyones diffrent... Good luck and have fun...
I always verify at 200 and 300 yards. I know guys always say 25 yards or 30 yards or whatever equate to a hit at 300 yards, but it is not always true. Trust but verify....
How tall are your sights above the boreline?
With a standard AR or M4, you should never be that high (4-5 in) above point of aim if you zero at 50 yards, which is one of the main reasons to zero at 50 yards (and wherever your rifle/ammo combination crosses again at 200 meters or so).
yea, a 200yd zero should be about 1"-1.5" high at 100 depending on load and exact sight height...
Quickly playing around w/ a calculator you'd have to have sights 5-6" off the bore to hit that high w/ a 50yd zero for a std 55gr load. maybe a scope mounted up on a carry handle??
Now a 25 yd zero will get you about that high at 100. maybe that's what he meant...

I am running a 6920 with fixed front sight and flip up rear. No other optics.
Give these targets a try. They will allow you to obtain a 50 yard zero if you only have access to a 25 yard range.
What you do is aim center mass on the sihloutte target. You adjust your group into the hash marked circle. This offset is calculated to give you a 50 yard zero.
Also, the adjustment grid is calibrated for carbine length sights, so it will take some of the guess work out of your adjustments.
