Living where I am in NJ we have not experienced the amount of pigs that changes them from hogs to varmints.... Once, in a Texas deer blind, I watched what looked like a black freight train pile through a hole in the fence and make its way to some deer feed and spooking the six or seven eating whitetails... With that in mind I`ll leave the floor (and pics) to the boys that truly have a varmint problem....
PS- Photo shows the "caboose" from the freight train I mentioned above...
