Barnaul .223/5.56, 55-grain, hollow point boat tail. These cartridges are imported from Russia and are new production. These fine cartridges are polymer-coated steel cased, non-corrosive and Berdan primed. These make for remarkable plinking ammo at a great price. Comes packaged 20 rounds per box, 25 boxes per case for a total of 500 rounds. These have a hollow point boat tail bullet for expansion and maximum stability in flight. They are pointed hollow points so they still feed great in all semi-auto .223/5.56 rifles. We sell this SKU by the 500 Round Case.
