44-40 Win – 225 Gr LFN – Magtech Cowboy Action (4440B) – 500 Rounds

Cowboy action shooters running 1873 replicas and single action revolvers need mild, accurate 44-40 loads in quantity, and Magtech’s Cowboy Action line was made for exactly that. This listing is Magtech Cowboy Action 44-40 Winchester 225 grain lead flat nose ammo, MPN 4440B, sold as 500 rounds for SASS matches and historical shooting.

Magtech rates this load at 755 fps with 285 ft-lbs of muzzle energy. The moderate velocity keeps recoil light for fast follow-up shots on steel and reduces wear on vintage-style actions. The 225 grain lead flat nose bullet is heavier than many cowboy loads, giving a solid ring on steel targets, and the flat nose profile is safe in tubular magazines. Lead bullets are for target shooting and competition, not hunting or self defense.

This ammunition fits revolvers and rifles chambered in 44-40 Winchester, also called 44 WCF, including Uberti and Cimarron 1873 Winchester replicas, the Uberti 1866 Yellowboy, Colt Single Action Army and Uberti Cattleman revolvers, and Marlin 1894 Cowboy models chambered for the cartridge. A common question is whether 44-40 is the same as 44 Magnum or 44 Special. It is not. The 44-40 is a bottleneck cartridge with different dimensions. Another common question is whether these loads are safe in original 19th century firearms. Antique guns should be evaluated by a gunsmith before firing any modern ammunition.

Magtech 4440B is new production ammunition, not reloads. Magtech is part of the CBC group of companies. Each round uses a reloadable brass case with a boxer primer and non-corrosive priming. This listing ships as 10 boxes of 50 rounds for a total of 500 rounds from one lot. 44-40 brass is thin and valuable to reloaders, so collect your cases after each match. A 500 round supply covers several monthly matches and the practice between them, and buying a single lot keeps your sight picture and point of impact consistent across both rifle and revolver.
