I sold my 10MM and have a box of new Starline large pistol primer 10MM brass. It has been stored in a dry place and as you can see in the picture it is clean and bright. I counted it just now and all 500 pieces are there. I would like to sell it all as 1 lot of 500 but will split it into 2 lots of 250. Asking $135 shipped for all 500 or $70 shipped per 250. USPS priority mail. Payment by USPS MO, Bank certified check, personal check held until clear, paypal and venmo.
