Anything heavier than 70 grains should have a 1:7 ratio or better. 70 grains is max for a 1:9 ration i believe.

Thanks for that. I’ve pretty much standardized on 62 grain projectiles be they FMJ, HP, or SP. I cant expect real distance accuracy out of an M-4gery anyway. That is what the M1A and the bolt guns are for.
