I have just over 1000 pieces of 300 blackout brass up for grabs. They are mixed headstamps, but they are ALL 300 blackout headstamped brass, no converted cases. They have been decapped, ss tumbled and polished in corncob. They have not been processed beyond that. Asking price is $105 shipped tyd. Will ship in a USPS flat rate box. Posted on other sites. Sold to first "I'll take it" OR PM timestamp.
