When I designed my cast bullets for the Taurus semi-autos, I tested them on all on live feral hogs. I trapped a bunch and selected those that had a body torso as large as mine. The pen was circular so I could control their direction and get them to a point that was 21' away. I would stir them up a bit so that they were agitated and then completed my test. With each of the cartridges; 32 Auto, 380 Auto, 9mm Luger, and 45 Auto; the terminal authority of two well placed shots was immediately fatal. The only reason I did not try my 25 Auto TL255-50-RF bullet was I ran out of hogs as I killed two to three with each cartridge. I still have the pen setup and this winter will catch a few and work with the 25 Auto.
I believe a feral hog is tougher to kill than a human.
