I have SEEN quite a few different big guys.

2nd yr bowhunting walking back from my stand at dusk and see a big wide, heavy white rack sticking out about 80 yards ahead of me...I would guess that one was 140+

Shotgun Hunting around 02, had a big guy run out about 50 yards through some thick stuff...I would guess he was like 140-150 also

The year I shot my biggest to date had a nice tall 10 run out straight away from me across a field...he would have gone over 140 for sure...and boy was he fast, haha.
