What a HOG. Congrats. I passed a deer in a similar circumstance about 15 years ago that I still regret daily. Half of what would have been a 250# 170" 8 pt at 15 yards dead to rights. Thinking he would be back next year huge with both horns. Only to learn later that he didn't grow a horn on the one side period. That deer really screwed the genetic pool up around my place. I do have 3 offspring of his on the wall though. If you can beat a mature old stud at his game you've got a great trophy regardless.
