October 6th of last year I took my biggest boar to date with the Springfield Armory 1911 Professional model in .45acp using Corbon 230 grain loads. The scale only went up to 375lbs but he topped it out. He had 5 /12 inch lowers adn 3+ inch uppers. It only took two shots, though he was dead from the first one and did not know it. He was the 186th feral hog.boar that I have taken with a 1911 in .45acp. I have never had a problem in harvesting them if I did my part and put the shot where it belonged.
I have also used the .45acp to harvest feral sheep, feral goats, javalina, bobcats and rabbits.
