Too many hogs to remember, damn near as many weapons as well but I'll give it a try.
Largest hog, 436 pound beast with 4.6" cutters taken with a .30/30 loaded with 150gr FP Corelokts on top of 31gr H322 at 45 or so yards. Folded up with a grunt. Old man and I were grunting MUCH more loading it!
Other firearms used has been: .270win, .30/06, .300wm, .444mar, 7mm.08, .220swift (was an opportunity with a behind the ear shot and only 130 pounder while yote hunting in Tx), .30/30 as already mentioned, a couple with .243, .44mag Rev, .357mag Rev, .500 S&W Rev, .50cal Muzzle Loader, .45cal Muzzle loader, 12ga slug gun.
Other methods: Longbow, Long Recurve, Compound bow, Catch dogs with knife (only done that a few times but thats a YOUNG mans game there).
