For pure fun, I like a .41, .44 or .45 caliber handgun. AR-15s work pretty well. I generally run 64-grain Nosler bonded solid base bullets in my .223 for big game and they do a lot of damage and penetrate like crazy. Something short and quick handling of roughly .308 power works well. This year I've primarily been using a .25-06 because I have a .25-06 Kimber Montana and a bunch of factory ammo and am too lazy to reload. The Kimber looks pretty beat because I've mistreated it and hunted it hard. It probably has around 100 rounds through it but almost all of those have been on game that has varied in size from coyote to elk. It is for me for some reason one of those guns that doesn't miss. Running or stationery, 40 yards or 400 yards, it gets the job done. Now that's a hog gun.
