I just got back from a hunting trip that has been 50 yrs in the making. Perhaps it is a little out of place on this list but it is,nonetheless, what I would call a classic single barreled sporting rifle
The load was 68 grs of Swiss 1.5 f and my own lube and a paper patched bullet of my own design. The rifle is a Ballard Pacific (#5) original, circa 1880.
This type of hunt is pretty hard on rifles and certainly, this one acquired additional, but honestly earned, "patina".
BTW, moose tastes better than any other member of the deer family that I've ever eaten (which includes all of them in NA except caribou)
