I am late to this party but to answer your original question, the 240 gr bullet will work great. However, I would recommend going with a 300 plus gr cast bullet with a wide meplate loaded to 1000-1200 fps. It will go through any hog at any angle and to me recoil is less than the 240 gr.
+1 on that! Shot placement will trump all else though. I would hate to tell you how many hogs I have killed with the Mighty .22 Mag off my mudboat or out the window of the truck, and fairly large ones too, 250+ lbs! A shot to the neck or under the ear and they were lights out. With a good heavy wide meplate hardcast you don't have to be a surgeon. As jamautry said. . .you can shoot them from any angle!
