seems like something fishy on that top hog, I've been following the progress on their FB page and it sounded like that same team was reprimanded last year for solicitation violation. Polygraph should tell the tale in the end.
I've literally killed thousands of feral hogs over the last 55+ years and anything over 250# is big, anything over 300# is uncommon, anything over 350# is very unique and rare, anything over 400# you better check your scale
I have a friend that has gotten big into hog hunting using thermal, kept bragging on all these 400+ monsters he was killing out of the corn fields around Lake Granger ... I told him he needs to buy a scale and start weighing them instead of just guessing. He gained a whole new respect for the weight of a hog's actual weight after getting that scale.
