[QUOTE="David Emerson, post: 1841499, member: 112579"] A gain twist distorts bullets.Especially long ones. It is common knowledge that a barrel that loses a little twist will shoot poorly. A barrel that is slightly gaining twist are supposed to shoot very well. I do not have the instrumentation to see if a barrel is gaining or losing twist. This is theory but I would think that a barrel that gains about a 1/8 of an inch twist would be the best. I read about a barrel maker in Canada that was making gain twist barrels. His name was Morrison if I remember correctly. Photos showed the rifling at the base widened out. To me that would not be desirable. S&W uses a gain twist in their 460 revolver but those are short bullets. [/QUOTE]
