RUAG Swiss P .50 BMG (12.7x99mm) 644 Grain Training SX Lead-Free Ammo
Military-grade precision sniper training ammunition engineered to match the trajectory and recoil profile of standard duty .50 BMG rounds while minimizing range hazardous exposure.

Product Overview
RUAG Ammotec Swiss P .50 BMG 644 grain Training SX ammunition (Part #25538768) is Swiss-engineered for elite military, law enforcement, and extreme long-range target shooters. Designed specifically for high-volume training on indoor and outdoor shooting ranges, this load provides identical trajectory and point-of-impact out to intermediate distances compared to standard tactical rounds, allowing shooters to train realistically without wearing out targets or contaminating ranges.
Featuring an innovative 644-grain Jacketed Soft Core (JSC) projectile with an aluminum-zinc alloy core, brass shoe, and zinc coating, this bullet is 100% lead-free. Operating at a velocity of 2,920 fps and generating over 12,200 ft-lbs of muzzle energy, it maintains sub-MOA precision standards expected from Swiss P sniper munitions. Paired with SINTOX® non-toxic primers and clean-burning propellants, it drastically reduces airborne pollutants and lead dust. Available in 10-round boxes or bulk 100-round M2A1 ammo cans.
