Has anyone tested how varying these two methods effect accuracy? I am wondering if it would be worthwhile to buy a collet type crimp die for rounds I fire in a semi auto 7.63x51. I have tried crimping my Grendel ammo, and found that I have to reduce powder charge to offset the extra pressure caused by the crimp.
The amount of crimp is dependent on a number of factors, so I think it is less precise than I like. I haven't found any significant shift in my bullets from cycling through the action, so going either way may not be necessary.
