Description

.44-40 Winchester represents one of the most storied cartridges in firearms history, and HSM loads this round the right way for modern cowboy action shooters and lever gun enthusiasts. With 50 rounds of new, non-corrosive ammunition loaded to moderate pressures, this box gives you reliable performance in both rifles and revolvers without punishing your shoulder or your ears.

HSM's Approach to Cowboy Action Loads

HSM Ammunition, based in Montana and making ammunition since 1968, specializes in this kind of traditional ammunition. Their Cowboy Action line respects the constraints of period-correct firearms while delivering the consistency you expect from modern manufacturing. The brass casings are reloadable, boxer-primed, and the rounds chamber smoothly in both vintage Winchester lever guns and Single Action Army-style revolvers. There's no corrosive residue to worry about, which means less cleaning headache at the range.

The .44-40's Dual-Purpose Design

What made the .44-40 legendary in the 1870s was the simple fact that you could carry one cartridge for your rifle and your revolver. That versatility never gets old. The 200-grain round nose flat point bullet was designed specifically for tubular magazines, ensuring that smooth feed reliability whether you're cycling through a Model 1873 or loading a Colt Peacemaker. The flat point design provides consistent accuracy without requiring special precautions like you'd need with pointed bullets in tube magazines.

Mild Recoil, Serious Accuracy

This load launches the 200-grain bullet at around 725 to 850 fps, depending on the source—velocities tuned for moderate recoil that lets you stay on target for fast follow-up shots. That matters in cowboy action competition where speed and accuracy both count. The harder lead construction helps the bullets hold together reliably, and the modest velocity means cleaner burning, which translates to less fouling in your gun and easier cleanup after the shoot.

Frequently Asked Questions

Will HSM Cowboy Action .44-40 ammo work in both rifles and revolvers?

Yes. The .44-40 Winchester was designed from the start as a dual-purpose cartridge for both rifles and revolvers, and this HSM load respects that tradition. The round nose flat point bullet feeds smoothly in lever-action rifles with tubular magazines and chambers reliably in single-action revolvers like the Colt Peacemaker and clones.

Can I reload the brass cases from this HSM .44-40 ammunition?

Absolutely. HSM uses quality brass with boxer primers specifically because these cartridges are meant to be reloaded. After you shoot them, deprime, resize, and reload them as you would any other handload. That reloadability makes this ammunition a better long-term value for frequent shooters.

Is this ammo suitable for vintage Winchester and Marlin lever guns?

Yes. HSM loads these rounds to moderate pressures that are safe in the classic 1873, 1892, and 1894 actions. The 725-850 fps velocity range is comparable to original black powder loads, so even older firearms in good mechanical condition handle this ammunition without issue. As always, have an older gun checked by a gunsmith if you're uncertain about its condition.

What makes the round nose flat point bullet design important for .44-40 cowboy loads?

The flat point prevents deformation in tubular magazines while feeding smoothly and reliably. This design has been standard for .44-40 since the 1870s because it works. The round nose portion reduces feeding friction, and the flat point delivers consistent accuracy while providing adequate power for the cartridge's intended ranges and targets.
