I have did a search but I thought I would confirm. So, I have a 7mm Mag with a custom barrel. I have been reloading for many years but mostly using RCBS dies. I am considering getting a Redding S type die. My fired win brass measures .315 outside diameter on all 5 I measured. The inside measures .2845, .286, .285 I am shooting Berger VLD Hunting that measure .283"
First question, can I assume my chamber is .315"?
So I measured my loaded rounds at .308 ,.310 ,.308 ,.3095
Case thickness of .0145 ,.013 ,.013 ,.013
Again Berger bullet dia of .283
So if my calcuations are correct and I want .002th neck tension i need a .305 / .306 / .307?
