It is not my defense load of choice but I have spoken with many farmers who keep a .22 just for killing hogs. The say it is the best for such an endeavor. I know that pigs have very dense skulls so this doen't make sense. Is the .22that good a round at penetration at close distances? I am not a farmer nor have I ever killed a hog but any input would be interesting. Wanna kill these ads? We can help!
