500rds – 5.56x45 Prvi Partizan Rangemaster 55gr. FMJBT Ammo

Prvi Partizan Ammunition 55 Grain Full Metal Jacket Boat Tail (FMJ-BT) Ammo Details

Prvi Partizan titled this 5.56x45mm ammo “Rangemaster.” Does that mean you will automatically take command over any range you fire it at? Sure! Why not? Just make sure to be respectful about it. No one likes a whip-cracker.

Everyone likes M193 spec ammo, though. It’s the most popular flavor of 5.56x45 (with M855 taking a distant second), and should prove plenty accurate out of any rifle that can chamber it (ideal rate of twist is 1:10” or 1:12”; not recommended for 223 Rem firearms). Prvi Partizan makes FMJBT bullets the right way: with nonmagnetic lead cores and brass jackets, plus optimally angled boat tails that maximize downrange velocity retention.

Rangemaster series ammo isn’t just good for shooting. It’s also good for handloading, which you’ll definitely want to do whenever you lay your hands on Prvi Partizan’s noncorrosive Boxer-primed virgin brass cases. This ammo is made in Serbia. You get four boxes when you order the 500-round case!
