Javelina Hunting is on my "To Do List", but I haven't been able to cross it off yet. Of course it's only been on the list for about 30 years, and I'm trying to get the really old items on the list taken care of first.
IMO anything 357 and larger is ok, but I prefer larger, especially at longer distances - like greater than 50 yards. I have purchased my HHH (hog hunting handgun) but I haven't drew blood with it yet - unless you count mine. Damn that S&W 460 is a handful!
