20 Rounds of 55gr FMJBT 5.56x45 Ammo by Prvi Partizan

Prvi Partizan pours an extraordinary amount quality into every Rangemaster 5.56x45 round. Each component in this cartridge is made of high-grade raw materials, carefully scrutinized throughout Prvi Partizan’s comprehensive quality assurance protocol, and assembled in accordance with military specifications.

This is standard ball ammo, precisely what target practice calls for. At 55 grains the bullet delivers a real familiar 3,240 fps muzzle velocity and its boat tail helps it resist wind deflection as it continues to exhibit superior speed downrange. (Expect a velocity of 1,566 fps at 500 yards, which is still nearly half of the round’s muzzle velocity.)

The FMJBT wears a concentric jacket around its evenly distributed lead core, so it possesses the in-flight rotational stability requisite for good accuracy. The jacket’s cannelure locks the bullet securely in its seating, so recoil doesn’t jerk it out of place. And Prvi Partizan doesn’t put any steel in their bullets, so you’re free to fire this ammo wherever magnetic loads are banned.

The nearly 100-year-old Serbian ammo producer loads their range rounds with clean-burning propellant and non-corrosive Boxer primers, as well as just recently minted brass cases. Are they reloadable? You bet they are!
