i never claimed to know it all and never will.i have hunted hogs20 years. i have hunted with spears,guns, and dogs.i even worked part time at owen's country sausage. i got to see first hand how hogs were killed every day.the head or skull is so thick that in order for a 22 to kill them it has to be almost placed against their head.a long shot away is extremelt rare.the bullet does not have the size or power to do that job.why would you even attempt such a shot?the probability of it killing are extremely slim.i love hunting and have been hunting for 42 years. i hunt hogs year around. i just got back from a 3 day hog hunt in palestine texas.when hunting a hog with a 22 you have to question your own personal ethics.unless you can get to where you can almost place the gun against the hog,you are more than likely going to just wound him.as hunters we have to make better choices.
