[QUOTE="Capt RB, post: 1511238, member: 85987"] The sooner you take a bullet out of yaw the more consistent it flies. Only way to do that is twist rate. Run the berger stability calculator and you will see increasing the velocity has a minor effect in the stability factor. Increase the twist rate and the number jumps. Over spinning the bullet without blowing it up will increase the bc of that bullet. It will also improve the transonic predictability for a firing solution. Ruger and Browning are offering a 9tw from the factory as of today. An 8tw in the 300win would be optimum for the heavy solids and the new 230 Sierria's. The 245 Bergers Idk about yet but it would seem they will like the faster twist. But they would also benefit from a bigger case like the rum or .590 case head cartridges. [/QUOTE]
