[QUOTE="benchracer, post: 1239089, member: 22069"] The 10 twist and heavy bullets are really only relevant in the .308 past 600 yards. If you are going to hunt mostly inside 300 yards, and occasionally out to 500, you will be just fine with an 11 or 12 twist. The 12 twist works just fine up to 185 grains or so. Though it can, and will, stabilize heavier bullets, you will lose enough bc with the 12 twist to negate the advantages of the higher bc offerings. For your stated uses, 11 or 12 twist will work just fine. If you were considering a heavy barrel rifle for F-class competition or the like, the 10 twist is a better choice. For hunting deer to 500 yards (or elk, for that matter) you will not be handicapped by a 12 twist. For your stated purposes, there really isn't much reason to go with a heavy bullet from a .308 case, especially if you intend to use bonded bullets. Your best performance will come from bullets in the 150 to 165 grain range. [/QUOTE]
