[QUOTE="Bart B, post: 500838, member: 5302"] I find it amazing, near unbelievable and surprising that gain twist barrel making has progressed to what the accuracy shown in these posts has been. I can imagine the centrifugal force on a bullet leaving at 3000 fps from a 6.5 twist spinning over 332,000 rpm is. After going to the Cutting Edge web site, it's clear as optical grade glass. I checked out the bullet design page and it was easy to see that gain twist rifling deforms only a small band around the bullet. The rest of the bullet's virtually unchanged by a 2X increase in twist rate. And those extra long bulletw will need a very fast twist, too. Being solid, they won't come apart spinning as fast as they do. Thanks for linking my mind to the modern bullets available. [/QUOTE]
