The PMC Bronze .50 BMG 660-grain Full Metal Jacket Boat-Tail (FMJBT) Brass 10-round box is a premier large-caliber centerfire rifle cartridge engineered specifically for long-range target shooting, heavy anti-materiel rifle training, and high-volume range exercise in .50 BMG platforms. A primary operational challenge when shooting military surplus or low-tier .50 BMG ball ammunition is inconsistent muzzle velocity and wide velocity spreads, which cause severe vertical dispersion, unpredictable downrange drop, and unstable flight through transonic regions. PMC resolves these external ballistic variations through strict computer-controlled powder measuring and tight manufacturing tolerances, providing shooters with consistent, repeatable trajectory performance at an accessible cost per round.
The foundational performance advantage relies on PMC's heavy 660-grain Full Metal Jacket Boat-Tail projectile. Featuring a precision-formed copper jacket enclosing a mild steel core, the bullet delivers high sectional density and structural integrity upon target contact. The streamlined boat-tail base drastically reduces rearward vacuum drag, yielding an impressive 0.701 G1 ballistic coefficient. This high aerodynamic efficiency minimizes atmospheric drag, flattens trajectory drop, and resists crosswind deflection during extended-range flight, making it a dependable choice for anti-materiel rifles and precision long-range target setups.
Propelling its 660-grain FMJBT projectile at a factory-rated 3,080 FPS muzzle velocity (generating over 13,000 ft-lbs of kinetic energy), this Bronze Series load maximizes the internal case capacity of the .50 BMG cartridge. Assembled in heavy-duty, precision-drawn virgin brass cases with non-corrosive Boxer primers and clean-burning propellants, the cartridge guarantees uniform chamber sealing, smooth extraction, and reliable cycling across bolt-action and semi-automatic systems (such as the Barrett M82/M107 and M99). The high-grade reloadable brass casings also ensure long service life for handloaders recovering fired brass.
