Hsm, Subsonic, 500 S W Magnum, Flat Nose, 590 Grain, 20 Rounds

The HSM Subsonic 500 SW Mag 590GR is a heavy-hitting subsonic load from HSM's Subsonic series, built to bring reliable performance to stout revolvers chambered in 500 S&W Magnum; with a 590-grain flat nose bullet this round stays below supersonic velocity for reduced noise signature and more consistent sound when used with a suppressor, while its mass delivers deep momentum and penetration that hunters and experienced handgun shooters appreciate for large game and brush work. You'll hear that the flat nose profile feeds and chambers smoothly in large-frame pistols and lever guns, resists deformation during handling, and helps transfer energy efficiently on contact without relying on high velocity, making it a go-to for situations where quiet, controllable heavy bullets are desired. The cartridge is reloadable for handloaders who want to tune performance, and the Subsonic model line from HSM is known among shooters for matching heavy-for-caliber bullets to conservative velocities to improve accuracy and terminal consistency at practical ranges, which makes this load excellent for range work, suppressed training, and field use where shot placement and penetration matter.
