I only 250 pieces and the bulk brass comes in a lot of 500. The price of the brass is $.19 cheaper buying it in bulk. The brass is 306.89 + 7.95 shipping for the 500 pieces, so the total would be $157.42 each. Add $10 for me to ship it to you so a total of $167.42 which is $.67 a round versus $.80 plus shipping it would normally run.
