|History of the .50 Remington cartridges ( 2 versions):
The .50 Remington a/k/a .50 Remington Army (M71) cartridge was the second version of this caliber. The first version: .50
Remington Navy (M67) was introduced in the U.S.A., around 1866 for the Navy Model 1867 (M67) rolling block pistol and
was a straight, with very slight taper, rim-fired cartridge and later as a straight walled center-fire case.
The later version (below) .50 Remington (M71) Army was a “bottle necked” case for the Remington Army Model 1871 rolling
block pistol introduced in 1870 had an “Inside Primed” Benet Cup internal primed center-fired cartridge.
Then later, sometime around 1873, the cartridge primer changed to an external primed (Martin Primed) and later to a regular, more
modern, outside primed case.
Ammunition was loaded by both Remington and Winchester and was available until about 1920, making this caliber obsolete for
over 96 years on regular primed and up to 146 years on inside primed at this writing.
The Army (M71) version has a large diameter projectile and will not fire in the Navy (M67) rolling block pistol.
