Sorry, Hoot, I have no experience with black powder. With a 1700 fps velocity I felt I would get better performance (20:1 alloy) for hunting than a metal jacketed bullet. Paper jacketing is more effort but has advantages for me.
The new brass I was working with is Norma not RWS as stated earlier. It was a cost issue and for this type of use I don't think it matters between the two brands.
I don't believe my rifle is nitro proofed either. Ross Seyfried's article on three of this class of cartridges is most useful information. Handloader #225 Black Powder Express Cartridges.
