Sig Sauer Supersonic CTT Brass .300 AAC Blackout 125 Grain 20-Rounds FMJ

Sig Sauer Supersonic CTT Features The Sig Sauer Supersonic CTT is loaded with a 125gr FMJ projectile with a G1 ballistic coefficient of 0.313 and a 21.31mm bullet length precision-loaded using state-of-the-art electromechanical monitoring for geometric conformity and consistent round-to-round performance. Optimized shell case metallurgy with premium primers delivers consistent bullet weight retention and minimal velocity variations across the full 20-round box making it a reliable practice load for suppressed 300 Blackout rifle platforms. The 2 145 fps muzzle velocity and 1 277 ft-lbs of muzzle energy from a 16 barrel deliver the flat-shooting supersonic performance the 300 Blackout cartridge is optimized for in rifle-length platforms. The 300 AAC Blackout FMJ cartridge is engineered specifically for superior accuracy and minimal dispersion when suppressed providing suppressed rifle shooters with a practice load that maintains consistent performance across extended range sessions without the cost of premium hunting or defensive ammunition. Precision electromechanical loading monitoring ensures geometric conformity for reliable feeding and extraction in semi-automatic 300 Blackout platforms across a wide range of barrel lengths. The non-staked non-lead-free construction reflects a conventional practice load profile optimized for high-volume training use.
