I have yet to fire it, it however is on my list of "to dos".
The one thing I love about a .45-70, it's a very versatile round, from the lower power cowboy loads, to the regular run of the mill trapdoor loadings, to the rip your arm off and kill a rabid rhino at your front door Garrett and Buffalo Bore max P+ loads. I have even used blackpowder loadings, over all, the caliber is one of my favorites.
