I've not killed many hogs, but I can tell you that they are not all that hard to kill, assuming good bullet placement. A .357 may not be optimum, but it will kill them. About a year ago, I worked up a .357 load for my Marlin 1894 carbine, using WW296 powder (same as H110) and 187gr. gas check hardcast bullet from Cast Performance. My load runs 1914 fps. from the carbine, and 1542 fps. from a 6" Ruger Security Six. It is a handful to shoot from a handgun, but it will poke holes through hogs efficiently. I would NOT recommend shooting this load from a K-frame, but L and N frames and Rugers should be fine. Keep in mind, a cast bullet can be run faster than a jacketed bullet of the same weight without getting excessive pressure.
