Ive killed 1, 2, 3, 4, and even 5 out of the same bunch starting with a 80 yard standing still shot and mopping the rest up on the run out to 400 or til i cant see em, with a .270 win and plowed em all. Bullet size is no replacement for proper shot placement. A .270 or 7 mm in capable hands is more than enough gun for anything out to 400 or 500 yards. Everyone is hung on the .30 caliber lately and frankly .30 cals are overrated. I can get the same job done with less recoil. Any outfitter that tells you you need a .30 cal to kill pigs is sadly mistaken.
