so if the hog is charging and you are in imminent danger go ahead and dispatch the hog. would you use a two tap or keep firing until you no longer feel threatend. i've seen some people in situations with hogs and russian boar and mixes with bows were i was glad i had my 30/30 or .44 for close encounters especially with mama and her little one's. as for how smart they are they are like cock roaches and can adapt to any enviorment and will eat anything. it seems like you shoot one and 30 more pop up. my buddy has about a 3 acre inclosure on his 500 acre place that he keeps nothing but ferral hogs and we usually shoot about 5 a month for a bbq and such or give them to the ranchhands,but it seems like you just throw water on them and they reproduce like damn gremlins.
