The HSM Subsonic 44 Magnum, 400 Grain Hard Cast Flat Nose, 20 RDs delivers a heavy, slow-moving .44 Magnum load tuned for smooth function and consistent subsonic performance. Each cartridge uses a 400 grain hard cast flat nose bullet with a Hi-Tek style coating, designed to run clean while maintaining reliable feeding in modern lever-action rifles and revolvers. Loaded to approximately 1000 feet per second from an 18 inch barrel, this round offers deep-driving energy without breaking the sound barrier.

This subsonic .44 Magnum load is ideal for shooters who want reduced report, especially when pairing with a suppressor, and for hunters working in close brush where predictable recoil and dependable penetration matter. Its consistent velocity and heavy bullet weight make it well suited for range work, field carry, and specialized hunting roles where quiet, controlled performance is preferred. HSM’s long-standing reputation since 1968 for carefully crafted ammunition is reflected in this purpose-built subsonic cartridge.
