ive never reformmed brass before can any one guide me through the process of making 7mm-08 from 243 or 308 cases.thank you in advance for your help.
Note what Clark said about " if ~~10% with the necks too thick are culled." That is true any time a case is necked down any significant amount. The case neck thickens and there may not be enough room at the chamber neck for case neck expansion. That can raise pressures enough to be dangerous.
The cases don't have to be discarded, just neck turned or reamed as necessary.
