On AR there is a discussion about the 45-70 not being enough for Bison. I disagree with that part but it is far from a good choice for 'any' soft skinned game. A rechamber to 450#2 or 450 3 1/4 and a recoil reducer would be a much better option.

I think that the two barrel set is pretty neat. I have never actually seen a Pederesoli. Is the workmanship equivalant to a $4500 Euro 9.3?
