MAC has a video on his channel where he gel tests the Lehigh bullet in 9mm but then shoots a feral hog that had already been killed and was propped up. He shot it broadside, he said through the shoulders but I thought the entrance seemed a big far back for that but in any case he did not get an exit from it. And that hog was not 20+ inches across.
Edit: Here it is. It was a test of the 90 grain 1500 fps load, not the Penetrator. It still did 20" in calibrated gel but not so much on the hog. https://www.youtube.com/watch?v=ClJcJ8LQFbQ&t=873s
