Here are a couple pictures of largest Oklahoma pigs that I have killed on our leases. These are free ranging hogs. It always amazes me when I here tales of people killing 400 and 500 Lb wild hogs, when very few people really weigh them. I am an engineer by trade so I do everything by the numbers. The brown pig weighed a whopping 225 lbs on the hoof; it was my biggest pig until this year. I killed the black pig this past rifle season and he weighed 190 lbs field dressed. I have weighed several pigs on the hoof and then after field dressing. Based on the data I have collected I use 1.29 times the field dress weight to calculate the live weight. Using that formula the black weighed 245lbs on the hoof.
