The HSM Magnuforce Subsonic .45 Long Colt 400gr 20 Rounds HSM-45C-10-N is a premium heavy-hitting subsonic ammunition specifically developed for hunters and shooters who demand maximum performance from their .45 Colt firearms. Loaded with a massive 400-grain bullet, this subsonic load delivers exceptional terminal ballistics while remaining quiet when paired with a suppressor. As part of HSM’s renowned Magnuforce line, this ammunition combines heavy bullet weight with subsonic velocities to provide superior penetration and stopping power in a .45 Long Colt platform.
Why Choose HSM Magnuforce Subsonic .45 Long Colt 400gr?
The .45 Long Colt is a classic cartridge with a long history of use in both revolvers and lever-action rifles. Most factory loads are designed for high velocity, resulting in loud reports and limited suppressor compatibility. The HSM Magnuforce Subsonic 400gr load changes the equation by offering true subsonic performance with one of the heaviest bullets available in .45 Colt. This makes it an outstanding choice for suppressed hunting, big game applications, and bear defense. The 400-grain bullet provides deep penetration and massive energy transfer, making it highly effective on large game such as deer, hogs, and black bear. When used with a quality suppressor, the reduced noise signature allows hunters to stay stealthy in the field. HSM loads each round with premium components to ensure consistent velocities, reliable ignition, and excellent accuracy from both revolvers and lever-action rifles chambered in .45 Colt.

Performance and Build Quality
The HSM Magnuforce Subsonic .45 Long Colt 400gr is built for hunters and shooters who require maximum stopping power in a subsonic package. The 400-grain bullet is significantly heavier than standard .45 Colt loads, providing exceptional momentum and deep penetration through thick hide and bone. This makes it particularly effective for hunting large game and for use as a defensive load against dangerous animals. Because the load is subsonic, it pairs exceptionally well with suppressors, dramatically reducing the report of the .45 Colt while maintaining impressive ballistic performance. HSM uses premium brass cases, reliable primers, and carefully selected powders to ensure consistent velocities and accuracy. Each round is crafted with attention to detail, resulting in ammunition that performs reliably in both revolvers and lever-action rifles. The 20-round box is perfect for hunters who want to carry enough ammunition for a hunt without excess bulk.
