Description
HSM's Cowboy Action line brings authentic old-school shooting to modern firearms. These rounds load to traditional pressures, making them ideal for anyone who wants to run .44 Magnum without dealing with the heavy recoil of full-power loads. The 200-grain hard-cast lead bullet uses a round nose flat point design, which matters more than you'd think if you're running them through a lever-action rifle or planning any cowboy action competition.
Why the Round Nose Flat Point Design
The RNFP bullet profile is the cornerstone of this load. It feeds smoothly through tubular magazines on lever rifles, eliminates the risk of primers getting pinched in the magazine tube, and cuts clean target holes that score well at the range. You get all that plus hard-cast construction that doesn't lead your bore.
Built for Competition and Fun Shooting
With a muzzle velocity of 975 fps and muzzle energy of 422 ft-lbs, these rounds generate just enough horsepower for reliable function in both pistols and rifles without punishing your hands during extended range sessions. The new brass cases are boxer-primed and reloadable, which means after you shoot them, you can reload if you're into that. The clean-burning smokeless powder and non-corrosive primers keep maintenance simple.
Whether you're training for SASS events, running drills on your lever gun, or just want affordable .44 Magnum ammo that shoots where you point it, this is solid ammunition. Made in the USA by HSM, a Montana manufacturer that's been building specialty rounds for over 50 years.

Frequently Asked Questions
Will these .44 Magnum cowboy loads work in my lever-action rifle?
Yes. The round nose flat point bullets are specifically designed to feed reliably through tubular magazines and won't cause primers to get pinched. They're a common choice for lever-action rifles chambered in .44 Magnum.
Are these reloadable?
Yes. These rounds use new brass cases with boxer primers, so they're fully reloadable if you reload your own ammunition.
What's the difference between cowboy action loads and standard .44 Magnum ammo?
Cowboy action rounds load to traditional pressures that are lower than full-power .44 Magnum loads. This means less recoil while maintaining reliable function and accuracy, making them better suited for extended shooting sessions and competition work.
Is HSM ammunition made in the USA?
Yes. HSM (Hunting Shack Munitions) is a Montana-based manufacturer founded in 1968 and is veteran-owned and operated.
