Great so I will trim after firing and before sizing.
I need to perform a pound casting on these rifles. I was wondering what to subtract so the boolit will release in the chamber. Then there is also spring back.
Just for example if the throat is .316 what would you size them at. I read if there is no space the pressure will spike and velocity will be erratic because space is needed to release the boolit consistently. And the thickness of the brass will need to be taken into account, correct?
thanks
