Working on a new varmit barrel 308 win. in 700 Remington 1 in 12 twist. I had one of these guns 15 to 20 years ago never could get it to shoot. i felt the twist was to slow because standard barrel hunting rifles had 1 in 10 twist. I messed around and got rid of a beautiful rifle. Now Remington still making this lazy twist so it must have been my gun. My question is what bullet weight do you guys shoot with this twist?
