HSM Subsonic .44 Magnum ammunition (brand part no. 44M19N) drives a 400-grain hard cast flat nose bullet to about 1000 feet per second from an 18-inch barrel, generating roughly 888 foot-pounds of energy while staying below the sound barrier. HSM coats the hard cast lead core in Hi-Tek Supercoat, a baked-on polymer finish that cuts down on smoke and bore leading without the added cost of a jacketed bullet. Because the bullet does not expand, it drives straight through heavy muscle and bone, a trait that makes this handgun ammunition load equally at home in a lever-action rifle or a big-bore revolver. For hunters and woods-walkers who want deep, reliable penetration on tough game, this subsonic .44 Magnum load is built for the job.
