Casings - Boxer-primed brass


This 5.56 NATO cartridge by Prvi Partizan sports an M855 projectile, which is a 62 grain bullet with a steel penetrator tip over a lead core in a full copper jacket. That green steel tip means more than that this round will attract a magnet; it also gives it superior penetrating abilities, but not so much that it’s classified as an armor piercing round by the ATF. Still, its steel tip and full metal jacket give this projectile more than its handsome share of penetrating properties, so with it you can have great fun drilling holes through metal targets from long distances.

Although this cartridge hails from a part of the world where the Soviet Union once had some influence, it does not reflect the fallen regime’s penchant for steel cased ammunition. As such, you may reload its Boxer primed brass casing multiple times, adding tremendous value to this purchase for the high-volume AR-15 shooter. Prvi Partizan makes great ammunition, a reputation to which the company owes their incredible popularity for all applications throughout the world.

A: Hi Dean. These rounds will work well in your Bushmaster. A boat tail bullet differs from a standard flat base bullet in that standard rifle bullets have what is called a flat base. With the common "flat base" design, the base of the bullet is flat. . Essentially, if you hold the bullet upright and you look at it from the side, the bottom of a flat base will have 90-degree angles at the corners. A boat tail bullet is tapered toward the base, narrowing slightly as the bullet reaches the base. This shape resembles the stern of a boat, which narrows slightly towards the back; hence the name “boat tail.” This improves the ballistics slightly for long range shooters. Give me a shout if you have any further questions. Ronnie 800-720-6035
