I am sorry. There is no way in hell a 40 cal will bounce off a hogs skull. I call shenanigans on that one. I have a buddy with a 22 mag revolver. drops them like a hot potato.
Lets look at the 40 for ballistic performance.

It even has superior performance thana 45 ACP.
Now lets look at my favorite hog round. The 22 mag. Right between the eye and ear or if facing you between the eyes and 2 to 3 inches up. drops em like a rock and they twitch. Here are the stats on that round.

50 gr (3.2 g) JHP 1,650 ft/s (500 m/s) 300 ft·lbf (410 J
Note that the .40 cal has around 50% better performance. Go whack a hog with pride.
