300 Blackout – Wolf Polyformance 145 Grain FMJ Steel Case – 500 Rounds

Wolf .300 BLK 145gr FMJ is a standard weight FMJ load suited for suppressed SBR use, home defense rifles, and subsonic shooting. At 145gr — the most common weight for this caliber, balancing velocity, recoil, and terminal performance. Full metal jacket — no expansion, consistent penetration, and reliable feeding in semi-autos. The standard for range training and high-volume practice. Steel-cased — harder on extractors than brass but significantly lower cost per round. Good for high-volume training where per-round price matters. The 500-round box works for stocking up without committing to a full case.
