[QUOTE="BountyHunter, post: 323088, member: 12"] Go to BR central and lot of posts on the gain twists. So yes they are using them. Peak pressure would be lower with a slower twist at the breech, but the computer programs like quickload cannot compensate for that as they are programmed only for standard factory twist like 1-10 in 30 cal and definitely not a gain twist. All things being equal, less peak pressure should allow slight MV advantage. It is also seen in the 5C or 5R type rifling with higher MV. BH [/QUOTE]
