If you are planning to shoot M80 Ball (147 grain FMJ) or any of the commercial jacketed bullets of about 150 grains as well as most cast bullets, then that 1 in 14″ pitch will be tops. I’ve not tried the 1 in 14″ twist with the heavy match bullets of 175 grains or heavier, so I can’t comment on that. When the 308 was still required for the Palma Matches, the 1 in 14″ twist was very popular with the 155 grain Sierra Palma bullet.
