I processed (deprime, remove crimp) 1k of mixed milsurp 7.62x51 brass over two miserable weekends to feed my FALs and custom Garand. I haven't had to trim the brass since getting the 'X' die set up. There has been no sign of internal problems in the brass either. I loooove milsurp brass (except when it has been fired in a loosely headspaced machine gun).
