RE: biggest that you have let walk
My last morning to hunt during the OK muzzleloader season I had 3 bucks (an 8, 9, and 10 point) in front of me at one time with a combined score of over 375", but not one of them was over 3.5. All three get to grow for another year.
The largest deer that I probably should have shot but passed was a 150 class 10 point, but he had a broken G2.
