How price per round is figured

Price per round is the pack price divided by the round count. Packs under 5 rounds, packs over 5000 rounds, and per-round figures outside the public band are left off the cards. Confirm the pack size on the dealer page before you buy.

Brass, steel, and bulk

Casing is not broken out on the current 300 BLK ammo rows. Read the product title on the dealer page. Bulk means 500 rounds or more, and a box is 50 rounds or fewer.

Where the purchase happens
