Shooting 55gr or lighter bullets on a 1:8 twist barrel
I own a M4 with a 1:7, and plan to buy something like a RRA LAR-15 Varmint A4 (Wylde chamber) with a 1:8 twist. I have observed for a 1:8 twist, optimum bullet weights range from 67 to 75 gr. But, I bet there are lighter/shorter bullets that can shoot sub-MOA on a 1:8 bbl. If you have had such an experience, I'd like to hear about it. Please, specify as much as you can about your rifle, bullet/cartridge (factory v. handload), muzzle velocities, and of course accuracy @ distance, etc.
