Subsonic suppressed shooting has gained great popularity in recent years for use in the field, at the range, or in self defense. The current commercially available subsonic .44 caliber ammunition is either the .44 special cartridge which can be fired in firearms chambered in .44 magnum, or a subsonic specific .44 magnum load with an off-the-shelf projectile weight of generally around 240 grains. Either way that leaves you with a fairly anemic 432 to 533 foot pounds of energy at the muzzle.
The development of our .44 magnum subsonic ammo took several years and many thousands of rounds fired. The 400 grain hard cast and coated Long Wide Nose flat point was developed specifically for our loading through trial and error. This subsonic cartridge has been extensively tested for safe chamber pressures, consistent shot to shot velocities and exceptional accuracy out of numerous factory rifles and revolvers. Last but not least you get your moneys worth with 888 foot pounds at the muzzle (1000fps with an 18” barrel), 1 to 1 ¼ MOA accuracy and an honest 200 yard effective range.
Here are some of the targets we generated during our year-long testing. We worked our way through numerous powder, primer, and projectile combinations in order to achieve the best accuracy and shot-to-shot velocity consistency, all the while pressure testing each and every combination to assure safe chamber pressures. Our primary test platforms were the Ruger 77/44 rifle with a 1:20 twist, and a Winchester lever action model 94AE with a 1:26 twist rate. Most testing for accuracy was done at 50 yards to minimize shooter error. Once the best load was determined we extended our shooting in 50 yard intervals, up to 200 yards, checking for bullet stability as the target’s distance increased.
This ammunition is loaded on state of the art automated loading equipment by HSM Munitions of Stevensville, Montana; then hand inspected to maximize quality control.
Now that you’ve seen how the ammo performs on paper and the loading process, please check out our demo video to see it in action. After a brief introduction you can see how it performs out at 200 yards.
We plan to film more demo videos available soon and have plans to get to the range in the near future.
Since not everyone shoots the .44 Magnum cartridge, we are developing ammunition for other calibers as well. Next? We’re currently testing a 500 Smith and Wesson, subsonic, with a 575 grain LWNFP bullet. It’s quiet and hits like. . . well, a huge chunk of lead.
