[QUOTE="Varminator 911, post: 413460, member: 9705"] Hey guys I'll take another shot at stating what I'm thinking. I'd say we're likely giving up terminal performance of our bullets in some cases by giving them minimal spin to gain accuracy at long range. The way I see it the guys that shoot cape buffalo and the like are the best experts on terminal bullet performance. They are going to 10 twists for bullets that are flight stable in 16-18 twist in say 458 and 510 caliber. This is for better straight line penetration on bullet impact. This has to have some implications for some of our bullets that we give minimal twist. Just because our game isn't dangerous or thick skin, I would still think hitting heavy bone or whatever might be a problem. In addition even for close range hunting with the long monometal bullets like Barnes I'm concerned that they might be flight stable but not impact stable. If I take a 150 TTSX against elk that's as much bullet penetration stress as a 300 TSX against a hippo. [/QUOTE]
