Most people vastly overestimate the size of pigs.
Last 3 hogs i've shot were 150-175 lbs. When I sent my buddy a picture of them, he thought they are 250 lbs.
He shot one 25years ago and the guide told him it was 225 lbs but his scale was broken. Over 25 years he's become a 300 pounder. I think he was actually about 200 lbs.
I've never killed one over 300 in the wild that were wild. Very few over 200
