Hsm Subsonic 500Sw Hitek 590Gr Hcfn 20/25

HSM Subsonic 500 S&W ammunition delivers heavy, slow-moving projectiles purpose-built for hunters and shooters who want maximum penetration with minimal noise. The 590-grain hard cast flat nose bullet, protected by HSM's Hi-Tek Supercoat, handles hard targets with the kind of bone-crushing authority that big-bore handgun hunters depend on. This subsonic load stays subsonic even from longer barrels, making it a smart choice for suppressed firearms or situations where you need the power of the .500 S&W without the report.

The flat nose profile maximizes energy transfer on medium and large game, while the hard cast construction resists deformation through heavy bone and dense tissue. Hi-Tek Supercoat reduces fouling and extends barrel life compared to bare lead alternatives—a practical benefit if you're running high volumes or shooting suppressed. At 1022 feet per second from a 16-inch barrel, this load generates 1369 foot-pounds of energy, delivering the stopping power that defines the .500 S&W platform.

Each box contains 20 rounds loaded to a cartridge overall length of 2.040 inches. HSM recommends a rifling twist of 1:32 or faster to stabilize the heavy projectile. Whether you're hunting hog or bear, or running suppressed pistol drills at the range, subsonic 500 S&W ammunition gives you a serious tool that shoots where you point it.

Frequently Asked Questions

Will this subsonic .500 S&W work in my revolver or handgun?

HSM notes this ammunition is suitable for all modern rifles and handguns chambered in .500 S&W Magnum. Always verify your firearm's chamber and consult your owner's manual before firing any ammunition.

What does subsonic mean, and why does it matter?

Subsonic ammunition travels below the speed of sound (roughly 1125 fps at sea level), which reduces the sharp crack that occurs when a bullet breaks the sound barrier. At 1022 fps from a 16-inch barrel, this load stays subsonic and is ideal for use with suppressors or in situations where controlling noise is a priority.

Why is Hi-Tek Supercoat better than plain lead bullets?

Hi-Tek Supercoat is a polymer coating that protects the hard cast lead bullet, reducing barrel fouling and copper/lead buildup in your bore. This makes cleanup easier and extends barrel life, especially beneficial if you shoot high volumes or run suppressed.

What game is appropriate for 590-grain .500 S&W subsonic ammunition?

The 590-grain flat nose bullet and 1369 foot-pounds of muzzle energy make this load suitable for hunting large, thick-skinned game. The hard cast construction ensures deep penetration and reliable performance on demanding targets.
