I would say go for more than a single shot, what if you got two pigs runnin by? I just bought a Rossi 44mag lever action 16" barrel, 8+1. Plenty of power, light (about 5lbs), and easily good out to 100 yards. Can really do some damage with the hornady lever evolution ammo.

x2 Yeah I`ve shot a marlin 44 mag with the leverloution rounds and it`ll kill anything you aim it at under about 200 yards..my cousin actually killed a spike with it last year at 320 yards.that`s probably not your ideal range for that gun though. I think it`s best as a brush-close range gun..jmo
