Reminds me of a hog hunt in Baker County FL, many years ago. I was after a big tusker, that had eluded me for years. Hunting in a swamp near the St Mary's River, I followed that darn hog deeper and deeper into the swamp, wading from hammock to hammock.
Finally, pulling myself up out of the water by climbing up a dangling limb, I found myself face to face with that dratted hog.
He charged, I shot. The 240 grain Sp from the 7 1/2 inch Flat Top Ruger took out the back of his skull. He landed on me at full speed, knocking me into the water, and pushing me below. I finally got untangled, and my head above water.
The hog was dead, I lost the darn Ruger for a bit in the water, and had to cut the thing up to get it the two miles back to the road.
Range was about 8 inches, so I guess a .44 mag is pretty effective at that distance
Personally, I recommend a little more distance between the hog and the hunter.
