[QUOTE="impalaSS, post: 1470618, member: 13519"] I recently posted a question about reloads in a glock in the handgun section. After reading some of the post about to much crimp increasing pressures it got me thinking. Is there any solid information on crimp pressure to pressure rise. Not saying this is a good idea or to try it. But therotically if you increased your crimp enough could you get more powder burn out of a shorter barrel. Like say an 18" 308 barrel you are loosing efficency because of the shorter barrel the bullet is out of the barrel before your powder finishing burning and reaches peak efficenc. So would more crimp hold the bullet in until your powder reaches a higher efficency level? Also could you get the same velocity with less powder and a tighter crimp, as more powder and no crimp in the same rifl?. I dont plan to try any of these theories and would not recomend them to anyone because it would be unsafe. I just found this interesting if there is any data or perhaps some of you know more about this. [/QUOTE]
