It is a good chambering. It's flatter shooting than the .45-70 it seems at least. But I do prefer the .45-70 for brush hunting grizzlys. What have you killed with yours Sawman?
I absolutely love this chambering. I really believe using the 300gr WFNGC (hard cast) or the Hornady 300gr XTP's this gun would get it done. I have killed some of the bigger animals with mine.
Best of luck with the sale of this great old gun sir. --- SAWMAN
