A near perfect box of UNOPENED, factory sealed, UMC 44 Henry Ammo Rimfire cartridges.  This box was manufactured after the UMC/Remington merger in 1911, showing the “Remington/UMC” in the red circle on the top label.  The end side labels of this box are also stamped “.44 Henry R.F.

History of the .44 Henry Rimfire Cartridge

One of the great reasons for the ultimate success of the Henry rifle, most notably the Henry Model 1860 repeating rifle, was the self-contained metallic .44 Henry cartridge.

In 1854, the Smith & Wesson Company had patented a lever action pistol using a toggle action and an integral front-loading magazine.  Unfortunately, the “rocket ball” ammunition used with this design left much to be desired.  Despite the limitations of rocket ball ammunition, the rocket ball was used in a number of attempts at making a commercially successful firearm.  As a result, this lead to the reorganization and creation of the Volcanic Repeating Arms Company.

During this Smith & Wesson reorganization, Oliver Winchester became a major stockholder. Smith & Wesson both dropped out of the Volcanic Arms Co. circa 1855-56 and Oliver Winchester reorganized, again, as the New Haven Arms Co. in 1857. Subsequently, Winchester hired B. Tyler Henry to improve the Volcanic design. Henry went one step further by improving the cartridge. He invented a copper cased self-contained cartridge which made the bullets more reliable. Accordingly, the .44 caliber Henry rimfire cartridge was born. With his new cartridge and S&W’s lever action design, he developed a new rifle. Thus, the Henry Rifle, using the .44 Henry rimfire cartridge, was the first reliable lever action rifle.

Otherwise known as the 1866 “yellowboy”, the improved Henry rifle was also chambered for the .44 Henry Rimfire cartridge.

Box wrapped in plastic for protection.
