Lineage
History
Benjamin Tyler Henry designed both the cartridge and the rifle simultaneously in 1860. The Henry rifle held 15+1 rounds of .44 Henry rimfire in a tubular magazine — an almost incomprehensible advantage over the single-shot muzzleloaders of the era. Union soldiers who could afford to purchase Henry rifles privately did so in large numbers during the Civil War; Confederate troops reportedly called it 'that damn Yankee rifle that you could load on Sunday and shoot all week.' The cartridge transitioned to the Winchester Model 1866 (the 'Yellow Boy') and remained in production until Winchester introduced the centerfire .44-40 WCF in 1873. Specialty manufacturers including Bertram produce cases for collectors today.
