[QUOTE="Lobber, post: 1444089, member: 95131"] Hello All, I’m preparing for a new build that will be chambered in 6.5x284 Norma with a long Deviant action. My question is regarding barrel twist. It looks like I should be able to get the particular barrel that I am interested in using in either a 1:8 or 1:7 twist (either a 22” or 24” barrel). I will be shooting some of the long VLD-style 140/142 grain bullets, but am also intrigued by some of the heavier 150-155 gr offerings that are starting to show up on the market, especially in a 6.5x284... It is my understanding that it would be unlikely that the 1:7 twist would “over-stabilize” these long bullets in the 140-155 grain range. However, I am a little concerned that the tighter twist may result in shorter barrel life with a cartridge already somewhat notorious for burning barrels a bit. Thanks for your help, and I look forward to the discussion. [/QUOTE]
