I figure if a 40 S&W launching a 155gr JHP and a 38spl +p launching a 148gr JHP both at 1100fps will do the job, then I think you have quite enough to dispatch a pig. Just pick your shot carefully. . . brain, neck, or heart.
As for hogs being bigger, tougher, and meaner. . . well, they can be bigger, but they're only mean when they're cornered or injured, and they die just as swiftly from bullets as anything else. . . I have yet to see anything shot at them "bounce off."
