As a kid I learned the only rifle rounds to be crimped were those shot in a Garand, M1 Carbine, or similar auto loading rifle. And Lever Action rifle.
Case Neck tension held bullets in w/o any crimp. Still do it that way.
Revolver ammo is roll crimped only enough to keep the bullets from moving forward in the case.
The only time I ever had any trouble was with a .454 Casull. It needed a heavy roll crimp and a Taper Crimp after that.
Auto loading handgun ammo got A very light TC.
