We have been using semi wadcutters out of a 357 on hogs for about 5 years now shooting 38 special swc ammo. They will drop them one shot but like anything else its where you hit them that matters. Even the 454 doesn't work if you hit them wrong. We have shot them with 30 cal carbine, 38spl, 357, 41 mag, 44mag, 45acp, 45lc and 454 out of handguns and the 38spl works as good as any except for maybe a slight edge to the 30 cal with soft points. Day in day out carry for hogs with us is the 357 with 38 special swc ammo.
