Another one of those hunts I know absolutely nothing about .... big pigs 'n bears.
But,
If hunting from a stand, would seem that one would have quite a bit of flexibility to place an accurate shot & drop the critter using standard deer/elk techniques/cartridges - no sweat.
But,
If having to hunt them on foot & have to deal with the possibility of a "close-encounter?" = I'd want one of the biggest, baddest rifle/shotgun heavy bullet load I could 1) accurately & 2) rapidly employ to break up the damned thing so it couldn't even get at me - ever, & forevermore
Screw killing it - I just want to break it up enough so it couldn't bite me!
Personally, I'me a pump-guy = I'd want some heavy-duty 12 gauge slugs, and/or a very heavy .30-06 760 pump rifle rounds - 200grs+ ... could be easily talked into .35 Remington, or beter - you make the call.
H&H = impressive & tell y'all what ... every pix of the big pigs I see, I just want to break 'em up.
Killin's for some time in the (very near future - hopefully) - I just don't want these (living) things anywhere near me!
