[QUOTE="alcesgigas, post: 1251387, member: 34925"] I've ordered a 32" heavy barrel in 338 with a 1:9.5 to 1:8 gain twist. My intention is to shoot monolithics--particularly CE 300 MTH--with best effect. My current barrel's chamber case length is 2.755 and I'm shooting 300 Berger OTMs' that finish up at 3.855 at .012 off the lands. Would I be better off chambering this barrel long to best accommodate the CE MTH which needs to seat 1.428 out? I'm figuring the base to rifling engagement should be 4.195 for a .012 offset. Also would this have a negative effect on jacketed bullets such as the Berger 300 OTM? [/QUOTE]
