I didn't get in early on this one, but agree that a smoothie would fit the bill--my choice would be a .54 smooth rifle. Loaded with shot it would take small game cleanly and a .54 ball is plenty for N.American big game. I don't have one, but if starting from scratch, that's what i would most likely build. If forced to pare my current collection down to one gun, I would probably have to keep my .45 PA longrifle, a rifle I built myself 25 years ago, and could not bear to let go--too much sweat and blood in it. My collection also includes a .32 TN squirrel rifle, a .40 PA longrifle, two .50 longrifles (one PA and one early southern), a .54 Lancaster in progress and a .62 smoothie. I usually carry the .50 early southern rifle for reenacting/rondys, etc.
