M1 barrel twist

[John Kepler]

Thanks, Cary. The reason I ask is that I won my choice of 300 Berger bullets, but all of their .30 cal, target and hunting, in the 150-168 range recommend 13-15 twist??

NO WAY! THOUSANDS of people have competed quite successfully with 168's in 1-10 TR barrels out to 600 yds. If you are attempting to shoot 1000 yds with a 155 gr Berger, then a 1-13 is a damn good idea (you have to kick it out of the rifle at 2900+ fps, and to do that you also need a 29-30" barrel....you ain't doin' it with a gas-gun!), but something tells me that you aren't looking to do that in a Garand!
