Alright, I need barrel makers, gunsmiths, smart fellers and tire kickers like me in on this.
Would a barrel that started out with NO twist and progressed to a normal twist over its length work? Say 1-1 to 1-8 over 28-30 inches. Instead of the bullet starting to turn prior to being fully engaged to the rifling, straight twist would allow the bullet to be fully in the rifling (dependent on length of the bearing surface) prior to it beginning to spin.
Is this even possible? Or has it already been tried and discarded?
Would this lower pressure (friction) at the throat?
Just thinking out loud here.
