I recently acquired a 45-85 cartridge made by U. M. C. The headstamp reads U. M. C. with S H straddling a small dimpled primer. It has a flat point lead bullet that APPEARS to be grooved length-wise. The case measures 2.100″ long. The overall length is 2.520″. I have gotten the idea that it may be for an early Marlin but would like credible info. BTW I have difficulty reading a micrometer. Don

It was a cartridge listed for the Marlin models 1881 and 1895, it was a 285gr loading for 45-70, I’m guessing a express cartridge with light bullet
1888 catalog for the 1881 and also listed later for 1895

It is as stated above a loading for 45-70 but with a shorter less grains bullet making the case hold more black powder. If it was for the 45-90 the case length would be 2.40″ long.
The 45-85 Marlin is not the same as the 45-85 WCF. As the Winchester in my mind is a true “express” cartridge. It has the hollow ended bullet with the express tube on the end and is made for chambers in the 45-90 WCF.

This cartridge is for the Marlin, Ballard and Colt Lightning rifles. The Winchester 45-85 is marked WCF and is the same length as the 45-90. This cartridge manufactured by Winchester is NOT marked WCF and is the same length as the 45-70. I would love to find a box for the Colt Lightning made by Winchester.
