HSM Subsonic 500 S&W Magnum ammunition (part no. 500SW11N) loads a massive 590-grain hard-cast flat-nose bullet coated in Hi-Tek Supercoat, built for shooters who want the 500’s raw bullet mass without the magnum-level blast and recoil. HSM holds this load to subsonic velocity, keeping the report noticeably quieter while the hard-cast, deep-penetrating bullet still carries serious energy downrange. The Hi-Tek Supercoat replaces traditional lube, resisting lead fouling and keeping the bore cleaner through a long range session. For handgun ammunition in the biggest production revolver caliber, this is the load for shooters who want penetration over expansion.
