While a .357 will take down a hog,the ONLY bullet you should use is a very hard cast(non expanding) bullet in a full power load. This to insure that any good spinal/head shot will drop it reliably with a .357. That's why I suggested a .41 magnum-it'll drop any hog ever to walk planet with a well placed shot. A .41 will recoil more than a .357 but is noticeably less than a .44 magnum,and completely controllable and pleasent to shoot.
