11.5” 1-7 twist AR bullet recommendation.

[markm]

Shooting an idpa target at 300 yards with 62gr gold dot, my hold was 2 mills on target, A zone hits. Again I’ma newb so if this sounds wrong it probably is but this is what I got.

Gold dots are not made for flight, so that 2 mils sounds about right from a shorty. The flattest shooting load known to man (in 5.56) is the 69gr TMK in 5.56 from Black Hills if that interests you.
