RE: ever missed a 15 yard shot
I shot a small buck at 15-feet once. I spined him because he was so close and I didn't allow for it when I shot.4 days later, I had another small 8 standing at 15-yards and, remembering the first one, I over-compensated and shot right under him. Lesson learned. Both were from the ground, btw.
I haven't missed another (yet). Well, at least not because of anything I did. I missed a whopper last year at about 7-yards, but that was equipment malfuntion due to user error (loose sight. ALWAYS check your equipment).
It happens. And it will again, to most of us at least. I always pray for a clean miss if I'm going tomiss at all.
