✅ SOLVED Can anyone ID this shell casing?

[Steve in PA]

I found this shell casing in West Texas near a post Civil War fort and town site. The casing has a bullet shoved into it nose first. By looking at the base of the bullet that is in the casing, I can see it matches this slug that was found nearby. The slug weighs 478 grains and is .50 caliber and 1.10" long. The casing is 1.77" long and .56" diameter.

Thanks, I did some research on the Government 50-70 and it seems to be the closest to what I have. However the weight of the bullet is about 28 grains or 2 grams higher than the spec for the original 50-70 and I can't find the length of the bullet by itself. I really don't know if the weight difference is meaningful or not. I will call this solved.

I would say not. I shoot black powder weapons and shoot all different weights of bullets from 180 Gn. to 350 Gn. on the same 100 Gn.powder charge. What changes is the trajectory and distance of each bullet. HH
