DD, it is neither. It is an original made 120 yrs ago and restored with some help from Ballard and many other people. It was pretty boogered when I got it. The wood is untouched however.
It is .38-72-300

That is one nice lookin rifle. I read that the 38-78-300 can be made from blown out 30-40 Kreg brass. Is that what you do?
