So I went and ran two different loads through a carbine this morning. 14.5” barrel, 16.1” including muzzle break. The 77gr smk load when I did load development was 3/4 moa at 700 in a ladder/ocw test, the loads were 23.9, 24.1, 24.3 I settled on the 24.1. The other load is a 62gr hpbt Hornady at 23.9. I know the sd and es is high, I loaded these on a 650. My question I guess is, are these fast enough? I was fairly happy with the 62s but the 77s seemed slow. They were 10 shot tests
