Could you kill a wild hog with .22 caliber rifle?

It's possible, but not recommended. A .22 caliber rifle is generally considered too small for hunting hog, and is not likely to humanely kill the animal. Hogs are tough animals and can require a larger caliber rifle, such as a .308 or .30-06, to ensure a quick and humane kill. If you do choose to hunt hog with a .22 caliber rifle, be sure to use hollow point ammunition and place your shots carefully.
