Any of the firearms you mentioned will work, but I'm partial to the 30/06 caliber. Pigs have good noses and ears so make sure you factor in the wind while hunting. I don't know what the laws are up there, but I enjoy hunting them in Texas under a full moon in open areas. Once they've been hunted a while, the big boys go nocturnal. Pistols are great, but I would make sureyou can climb a tree if needed. They will come after you!
