For suppressed firearms, the HSM Subsonic .44 Magnum 280gr HCFN, 20-Round Box (brand part no. 44M20N) gives HSM shooters a .44 Magnum option that is tuned to stay below the sound barrier for quiet, suppressed shooting. Each round drives a 280-grain hard cast flat nose with Hi-Tek Supercoat bullet at roughly 1025 fps out of the muzzle. It is a dependable option for anyone stocking up on handgun ammunition.

Key Specifications

• The chambering is .44 Magnum, a chambering purpose-built to run quiet subsonic loads through a suppressor.
• The bullet weighs 280 grains, a heavy-for-caliber weight that keeps the bullet subsonic while retaining energy.
• The bullet is a hard cast flat nose with Hi-Tek Supercoat, a cast design built to punch straight through heavy muscle and bone.
• The harder cast alloy resists leading in the bore even at elevated velocity, which keeps accuracy consistent shot after shot.
• Muzzle velocity runs about 1025 fps, kept intentionally below the sound barrier for quiet operation.
• Each box holds 20 rounds, enough to run a full suppressed range session.
• Cost per round runs about $1.42, useful for budgeting a range day or a season of practice.
• The Hi-Tek Supercoat polymer coating replaces traditional lubricant, cutting down on bore leading and smoke compared to a plain hard cast bullet.

Frequently Asked Questions

Do I need a suppressor to shoot the HSM Subsonic .44 Magnum? No, it will cycle in any properly functioning firearm chambered for it, but it’s loaded specifically to stay below the speed of sound, so it’s quietest and most effective through a suppressed barrel.

Does the hard cast flat nose with Hi-Tek Supercoat expand on impact? No, it’s a non-expanding, deep-penetrating design built to drive straight through rather than mushroom, which is the point on tough game or through barriers.

How many rounds come in a box? Each box holds 20 rounds.
