i am taking my young cousins hunting for the first time this year. i am hoping to get them both a shot at a pig. i was wondering what gun was the best for them to shoot that could make a good, clean kill on a hog. one is 12 and the other is 15. we will be hunting from a ground blind so a long shot is not very likely. i have a 30-06 which i think is too much of a gun for them to handle. i also have a 12, 20 and .410 shotgun and a .22 lr. which gun would be good for them? and if a shot gun would buck shot or slugs be better? also, is it better to head shoot hogs or shoot them in the vitals?
