Thread: Crimping ttsx's

Rounds in a magazine are subject to significant forces under recoil. This can cause the projectile to move if the neck tension isn't enough.

Changing the neck tension should/could change the pressure and performance of the "wicked" load. Watch the pressure if you change this.

I hard to change the tension on he 223 Maximus. The brass had thinned out in the necks and the Colette Die wouldn't give enough, I put the decapping rod in the drill and give it a rub with some emery paper to take a little off.
