About this load
Magtech .300 BLK 123gr FMJ is a standard weight FMJ load suited for suppressed SBR use, home defense rifles, and subsonic shooting. At 123gr — 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. The 500-round box works for stocking up without committing to a full case.
