Hello,
So if we assume after firing, brass springs back 0.001”, and fired brass measures x.x90” with a given comparator, then we assume the chamber is x.x91”? And for bolt action rifles, bumping the shoulder 0.002” means sizing the cases to x.x89” to give chamber clearance of 0.002”? Or does bumping the shoulder 0.002” mean set the die to make the brass measure x.x88”?
Thanks,
Mat
