If you can find Berdan primers, the fuss to deprime is jsut not worth it IMO, the pirmers will likely be double boxer primers, so the brass just isn't worth keeping when once fired brass is available cheap. A berdan primed case has two flash holes. While you could mill or bor ethe primer pocket anvil out, the twin flash holes coul dcause you all kinds of trouble. Once fired 308 is available for $210/K. 1K bedan primers could run you $100 if you can find them, just not worth the effort or cost IMO. If you still want to go forward, e-mail Graf's, see if they can order them for you.
