On the eve of my move to Alaska I'm having a little trouble deciding on a go to rifle. I'm considering a pedersoli Sharps.54 Cal paper cartridge rifle. Does anyone have experience with this rifle or rifles loaded with similar loads (80gr of triple7 ahead of a RB or conical)? Will it be effective against moose and browns out to 100yds with good accuracy? And for the record centerfire is not an option black powder only.
