But don't shoot cast lead projectiles through a sealed can. (Which means don't shoot cast lead projectiles out of a rifle suppressor, as almost none of them are user serviceable.)
1. water dropped so about 13 on BIN scale1st I would guess it depends on how hard the cast bullets are! 2nd what's the resalability of a used suppressor? 3rd what velocities are you running in .308 & 300 B.O.?
I shoot cheap lead bullets thru my .22 cans, but they do come apart to clean. Even after running .22 on full auto my Spectre II does not seem to be overly bad.
