45-70 govt. bullet question

Could someone tell me how many different bullets were used in the manufacture of the 45-70 Government cartridge for the military. I’m not talking about the experimental types. Just the ones used by our U.S. military.

The standard military bullets were the 405 gr. and 500 gr. round-nosed lead bullets. The 405 was introduced with the cartridge in 1873 and was loaded with both rifle (70 gr.) and carbine (55 gr.) black powder charges. About 1881 the 500 gr. bullet was introduced for the rifle, and retained the original 70 gr. powder charge. Jack

Thanks Jack!
