Be sure to polish up on the hog anatomy too. Shot placement is crucial. Hogs have thick skulls, think of a football player-helmet and pads. They are most vulnerable behind/in the ear, eyes and snout. Also, mid-upper back-lung/spine shot. I have avidly hunted hogs since 2005, killing roughly 2100. In tight fields/cut overs, I carry a Browning Auto 5 12ga, loaded with slugs and 000. Over open fields, I use a choice of 3- 100 yards in, my .17 Savage bolt action or Henry .22mag lever action do the trick fine. I also use a Marlin .45/70 lever action, 450gr. compressed load, non-hollow point. Depends on the size pigs I have seen in a particular area. Over 100, my Mini 14 or .270. I am very careful with my weaponry as a thru shot can easily travel and hit other non-targeted livestock. Keep in mind, they do not see or hear well but there sense of smell is extremely keen. Most times they are not charging you, just running wild, you happen to be in the way. The only time I have had pigs defend themselves is either trapped, wounded or protecting piglets. As for the meat, I do not care to clean it and have enough to spare. I donate it to local folks who can use it more than me. I kill the pig, make a couple calls and it is gone.
