The HSM Subsonic .45 LC ammunition with 400-grain Hi-Tek hard cast bullets is built for shooters who want serious power without the report. This subsonic .45 LC round delivers 880 foot-pounds of energy at 1000 feet per second from an 18-inch barrel—enough stopping authority for hunting and sport shooting while keeping velocity below the sound barrier. The hard cast, flat nose projectile with Hi-Tek Supercoat provides reliable penetration and minimal fouling, making it a practical choice for handgun hunters and lever-action rifle users who demand dependable performance.
HSM engineered this load with specific firearm compatibility in mind. The 1.625-inch cartridge overall length fits standard .45 LC chambers, and the hard cast construction suits the magnum revolvers and modern lever guns that typically chamber this caliber. The Hi-Tek coating reduces fouling and cleanup—a real benefit for high-volume shooters or those using suppressed firearms where subsonic rounds shine.
Whether you're hunting with a lever gun, shooting a Ruger Blackhawk or Redhawk, or running a Contender pistol, HSM's subsonic formula gives you the velocity you need with the stealth you want. For handloaders, reloaders, and shooters who value American-made ammunition tuned to classic and modern platforms alike, this is a no-compromise load.
| Caliber | .45 LC (Long Colt) |
| Bullet Weight | 400 grains |
| Bullet Type | Hard cast flat nose with Hi-Tek Supercoat |
| Muzzle Velocity | 1000 feet per second (from 18-inch barrel) |
| Muzzle Energy | 880 foot-pounds |
| Cartridge Overall Length | 1.625 inches |
| Rounds Per Box | 20 |
| Boxes Per Case | 20 |
| Recommended Rifling Twist | 1:30 or faster |
HSM designed this load for modern lever-action rifles, Ruger Blackhawk and Redhawk revolvers, and Thompson Contender pistols. All modern lever guns chambered in .45 LC will safely fire this round. For revolver use, check that your specific model is rated for .45 LC.
Subsonic rounds stay below the sound barrier, reducing noise signature—especially important if you use a suppressor or hunt in noise-sensitive areas. At 1000 fps, HSM's subsonic load still delivers 880 foot-pounds of energy, plenty for hunting applications within typical .45 LC ranges.
The Hi-Tek coating on the hard cast bullet reduces fouling, leading, and copper buildup in the barrel. This means less cleanup after shooting and better longevity for your firearms, particularly valuable for high-volume shooters.
HSM recommends a 1:30 or faster rifling twist rate for this 400-grain bullet. Confirm your rifle's twist spec before purchasing to ensure reliable accuracy and performance.
