AR 15 T91 out to 476 yards 55gr 62gr 77gr match bullets zeroing in scope

interesting how the 62 gr green tip did very well i think a longer barrel say 20 inch is needed for the 77 gr match rounds to preform better

Probably has more to do with the twist rate in the barrel rather than the length of the barrel. 77's need a very fast twist to stabilize.

alls good. Be careful on public lands as hikers could still come thru.

I agree with Blackdog above the faster twist rate is needed on the heavier bullets.
