Is the Remington/Winchester 3rd iteration of the black powder 44/77 rimed cartridge a very collectable round? These have a 355gr lead bullet over 90gr of BP with a very large primer. Your thoughts!
I'm a cartridge collector and I've never seen a .44-77 although they are out there. It is certainly a collectable, probably in the $10-20 range per cartridge.
You might try some of the cartridge dealers online for more information.
You might post your collectible ammunition value questions on the International Ammunition Association site. That's where all the ammo collectors hang out. COTW has a little to say about the .44-70, mainly that it was a round for both Sharps and Remington-Hepburn #3 rifles, and was loaded with a variety of bullet weights. I have not seen one.
These were produced by Remington (and their various divisions) Sharps and Winchester. The brand will affect the price! I also believe the 44-77 is the same case as the 43 Spanish military round, which explains why you never see one, when the surplus rifles hit this country, any reloadable ammo was used up.
I've seen 44-77 cartridges in other collections, but, alas, not in my own. I've also seen 44-77 Hepburn rifles, original as well as rebarreled, in BPCRS competition, though with modern brass. I was really into single shot rifles and cartridge collecting at one time and got to see a lot of unique guns and cartridges.
If you have a 44-77 cartridge for your collection, treasure it.
Both COTW and Donnelley's book make mention that factory (Remington) reloadable two-piece cases with a steel head for the .44-77 are known. COTW also says the .44-77 was inspired by the .42 Russian and .43 Spanish cases.
