If that's an original "Cattleman's Carbine" that's pretty interesting. It is made up ofa Remington 1858 black powder revolver, longer barrel, and a wooden stock. I have that same revolver without the stock and the longer barrel. I load 25 grains of Goex 3f and a .451 un patched roundball. I also use a wad on top of the powder charge. Accuracy is excellent but you're right about the power of the revolver, it might be lacking a little for big game hunting.

Although, with that longer barrel, if the deer were close, say 25 yards, I think a person could sneak a ball out of that into the right place and take one down. I'd have to reread that laws of our State. With an 18 inch barrel, then counting the cylinder length, that might actually be a legal huntingRIFLE in our State.It would be exciting to try and take one with somethinglike that.
