Guns and Ammo Magazine has a sort article on crimping. Though its focus is on wheel gun the author did mention that lead bullets are more likely to move than jacketed bullets. The test was for three types of crimps. Light, medium and heavy on a 44 magnum cartridge. He fired 5 rounds and measured the 6th for shrinkage. None was noted on any of the jacketed bullets.

I am still wondering, from a reloaders standpoint, if this occurrence has more to do with ammo construction that firearm chambering the round. I read elsewhere that the loading ramp could cause bullet setback.
