I have just tried out this new collet die. It really works well. Don't know if it will make a lot of difference.

I`m sure you will like it.If you happen to have a factory crimp die at hand you might wanna "snug"the bullet in the case.Works well for me.

I've been wanting one for months now, but day-amn, the suckers aren't cheap. Still, I'll probably get one eventually for my belted magnums.
