Anybody with a 22-250 Ackley, I'd like to find out how much the case length shortens when you fire form.

Thanks in advance.
 
Re: 22-250 Ackley question

I've seen anywhere between .003" and .010" reduction after fire forming. It really depends on the brass itself. The softer Winchester brass seems to lose a little more than Lapua does from what I've seen.
