You can always consider a 20 ga double barrel or single barrel. If deer and other big game are occasional and small game are your focus, then the shotgun seems like a good all-around gun. I just put a rear sight on my Pedersoli 12 ga and am hoping to test out the windage/elevation this weekend if the weather permits. In my state of CA, a double barrel wouldn't be legal during muzzleloader only seasons since it has 2 barrels. But a single barrel, like the TC New Englander might be right up your alley. #6 shot would do fine for small game and a .600 roundball would drop a moose.
