DCRA TR(F) rules state max bullet weight of 156 gr. for .308. plenty of twist for that bullet weight. The twist will also work with 175 gr bullets.
Most TR/Palma shooters are shooting barrels around 12-14 inch twist but a few are shooting 10-11 inch twist.
I just ordered 4 barrels from Bartlein(not all for me) all 30 cal all 1:12 twist intended for shooting 155 gr bullets.
