HSM Subsonic .45 Long Colt ammunition (brand part no. 45C10N) loads a 400-grain hard cast lead flat nose bullet built to stay under the speed of sound, making it a natural match for suppressed lever guns and revolvers. HSM coats the bullet in Hi-Tek Supercoat, a dry-film lubricant that cuts leading and keeps bores cleaner than traditional lead. The heavy 400-grain weight and flat nose profile favor big-bore hunters and cowboy-action shooters who want reliable expansion-free penetration. In rifle ammunition, this load is built for shooters running suppressed or subsonic .45 Colt setups.
