I just bought a 45-70 CVA scout to convert
Coolest gun in their line up too. Hard to believe they can make a SS frame CF and sell it for less than the 2 upper end ML offerings. On top of that its almost as light and has a removable muzzle brake.
I wish you had some big ole conicals to try in it. I bet it would be a hoot with a 465gr and about 75gr of powder. That would be a killer "brush gun" load.
