looking to get the age of this bullet if anyone can help please....I understand the headstamp as UMC= Union Metallic Coy, Bridgeport C.T. USA.
S H=solid head .....thanks paul.45 70 001.JPG45 70 004.JPG
 
It was listed in a book about Military Cartridges, so I think it is probably a Military Cartridge.
 
That's a 45-70-500. It is pre-1912 when the headstamp would have changed to REM-UMC.

It is both a commercial and military cartridge. From the late 19th Century until the end of WW 1, the major suppliers of 45-70 ammunition for the US Government were contractors such as UMC, REM, WIN, etc.

Looks like 45-70 for Springfield Trapdoor. The cartridge is sopt on similar, but the trapdoor is model 1873 but of course went through the shellacing of upgrades throughout
 
The Cal .45 Rifle and Carbine cartridges were developed for the "Trapdoor" in 1873 but they have been used in a wide variety of other rifles for the next 141 years. The 45-70, as it exists today, is not much different than it was when first loaded. It's made from more modern materials (brass), and uses a Boxer primer rather than the original Benet, but it's basically the same cartridge.

Here's a lineup of the original military loads (Frankford Arsenal), from 1873 to 1895.
