antique 45-70 rounds

[spurdude]

I found at an auction. about 20 rounds marked U.S.C. Co. (United States Cartridge Company) I sacrificed one round and took it apart just to see what we had. here it is: A 500 grain lead round nosed bullet with 3 grooves, a hollow base with a small hole up into the center. some bullet lube on the bullet, no wad, looked like a black powder ffg compressed very hard. measured about 65 grains on volume measure. no over primer wad. a typical brass case with a roll crimp. So I am assuming if the primers are good the gun will go boom when it is fired. I'm currious to see the accuracy of this simple round. however, they have a historical value so I'm not sure if I want to try to shoot them. any thoughts?

65 grains of FF under the 'government bullet' is already known to be a good-shooting load.
Keep the old rounds for their historical value.
