Got a custom build back, 7mm WSM, Krieger MTU, surgeon action. I shot it , reloaded by neck sizing only, shot some more, then sent the brass to Warner Tool so he can make me a custom insert for my warner die. He said that it definitely was not a standard 7 WSM chambering after carefully measuring the shoulder angle on the twice fired cases I sent him. Should I just bump the shoulder with a FL die and keep shooting it? I wonder if this will overwork my brass? Do I need to just shut up and shoot it anyway? Thanks ya'll
