Ive read somewhere, to bump shoulders back 4-6 thousandths for AR cartridges. Last night I was sizing some 223 brass for my 223wylde. With 1/4 turn camover, the shoulders were bumped .010”. With no cam over the shoulders were .002”. With minimal cam over the shoulders were bumped .007”, so I left it like that. How far do you guys bump the shoulders on your 223 AR brass?
