I came across a box of old ammo that included two rounds of 22-15-60 U.M.C. (thats what is on the bottom of the casing) I have never seen that before. Can anyone give me some info? I'll try and provide a pic
We all make choices, some good, some bad, can you live up to yours?
A long skinny center fire case developed by the Stevens company in 1896 for the Stevens model 44 or 44&1/2 target single shots. The case was 22 caliber, made to utilize 15 grains of powder and was loaded with a 60 grain bullet. As a black powder cartridge it proved unsuitable for target use because the bores fouled too badly. It was made for a .226 bullet. In muzzle energy it was the equivalent of the modern 22LR loadings. A few years later, when rim fire 22's came loaded with smokeless, the 22-15-60 fell into disuse.
The union Metallic Cartridge Company was founded by Marcellus Hartley in 1867. In 1888, Hartley purchased Remington. In 1912, The two companies were merged into Remington-UMC. In 1933, The Dupont company purchased a controlling interest in Remington. A year later, Remington purchased the Peters Cartridge Company and became Remington-Peters.
If you check the stamping on some of the Remington rim fire cartridges some still are stamped with a U for UMC. Like the way some Winchester rim fire is stamped with an H for Henry.
