WSM users

[English]

just a quick question to those who use this chambering.I personally run a 7mm WSM after finding out the powder i use dont like magnum primers Iam still getting it quite hard to re chamber a once fired round,the primer is not showing any signs of pressure and Iam not running a hot load,61gr RL19 162 gr A Max)
so the question is do you need to body size the brass every firing ???

English, my observations have been that if you use an extruded powder you dont need a magnum primer. If you use ball,sphirical or a SSC powder the magnums work better because of the powder density.
As far as full legth sizing every time, I dont have to untill the 5th reload. I bump the shoulder .002 and size the neck and I'm GTG. I think you may br encountering some headspace problems, bump the shoulder .002 to .003 and you should be fine.

may I ask what you are using to bump the shoulder with
