HSM's Magnuforce Subsonic load brings real stopping power to the .45 Long Colt cartridge without the loud report. Using a 400-grain hard-cast long flat nose bullet driven to approximately 1000 feet per second, this round stays safely below the sound barrier for quieter shooting, especially when paired with a suppressor. The heavy bullet weight gives you serious energy on target while the moderate velocity means softer recoil and less wear on your firearm.
The Hi-Tek protective coating encapsulates the hard-cast projectile, reducing barrel fouling and leading while eliminating the mess of traditional wax lubes. You get cleaner hands, less smoke at the range, and easier firearm maintenance between sessions. This coating also means you can run these rounds through your press without gumming up your reloading dies if you recycle the brass.
HSM loads these cartridges with temperature-stable powders and tests each lot for consistent subsonic velocities. That means whether you're shooting in cold weather or during summer heat, you'll get reliable performance shot after shot. The flat-nose bullet profile feeds reliably and delivers the kind of straight-line penetration you need from a subsonic round. Each box contains 20 rounds of quality ammunition with new brass cases and boxer primers, making it reloadable for those who want to stretch their dollar further.
Whether you're running a bolt-action rifle, lever gun, or semi-auto, this load works well for hunting, target practice, and anyone who values noise reduction without sacrificing power. The 400-grain projectile packs real energy for close to medium range applications.
Yes, this load is specifically designed for suppressed shooting. Loaded to approximately 1000 fps, it stays safely below the sound barrier even in cold conditions. When paired with a quality suppressor on a bolt-action or semi-auto rifle, you'll get the quietest shooting experience. Without a suppressor, the subsonic velocity reduces noise compared to standard loads, but you should still use hearing protection.
The Hi-Tek coating molecularly bonds to the hard-cast lead projectile, creating a protective shell that prevents barrel leading and fouling. This means less smoke, a cleaner bore, easier maintenance, and no greasy residue on your hands or reloading equipment. You get the cost benefits of hard-cast bullets with performance closer to jacketed rounds.
Yes. These rounds use new brass cases with boxer primers, making them fully reloadable. Just deprime, clean, resize, and reload the cases using appropriate .45 Long Colt load data. The Hi-Tek coating means less fouling buildup in your die, which is an added benefit when processing fired brass.
This ammunition is suitable for any rifle or handgun chambered in .45 Long Colt, including bolt-action rifles, lever-action carbines, semi-auto platforms, and revolvers. However, subsonic rounds work best in bolt-action and lever-action guns or in semi-autos with adjustable gas systems or delayed blowback designs that cycle reliably at lower velocities.
