1000 Rounds of 55gr FMJ 5.56x45 M193 Ammo by Prvi Partizan

The 5.56x45mm is an intermediate rifle cartridge that’s been on the market since 1963. It was originally designed for the military’s M16; under STANAG 4172 it’s listed as one of the standard NATO rounds and is also used by militaries in countries not part of NATO. There’s been some confusion regarding the visual similarities between the 5.56 and the .223, so here’s reality: on the outside the two cartridges are, indeed, nearly identical. But on the inside they’re different; the 5.56 is loaded to a significantly higher pressure and the chamber leade of the .223 is shorter. So while you could fire .223 rounds through your 5.56-chambered rifle, it isn’t a great plan to run them in reverse.

These 5.56 rounds are made by Prvi Partizan, a company that was founded in 1928 for the purpose of supplying the local military. Today the company produces ammunition for the general public on a global level, making everything from hunting rounds to small arms ammunition. They continue to supply their military and law enforcement agencies with ammunition; in fact, they’re the Serbian Army’s sole supplier. Prvi Partizan – which is often shortened to PPU – has a reputation for manufacturing good target ammunition at reasonable prices.

At 55 grain these are pretty lightweight rounds for the 5.56, meaning they’ll fly down-range at higher speeds and are light enough not to increase your felt recoil. These are Full Metal Jacket Boat Tail – FMJBT – rounds, so they don’t expand on impact, and the BT means they’re better able to resist cross-winds and deliver a flatter trajectory. Each round leaves the barrel of your rifle at a muzzle velocity of 3248 feet per second and hits home with a muzzle energy of 1283 foot-pounds. There are 1000 rounds in this box; ammunition is manufactured at the PPU plant in Uzice, Serbia. This ammunition is best for target practice, tactical training, and plinking. Order now and prepare to spend some serious time heating up your 5.56.
