RE: Has this ever happened before...not prepared?
Confused the heck out of me when my buddy tried to explain it to me on the range. It took some convincing on his part for me to put my 40 yard pin on a five yard target.
I put my 40 yard pin on a target 5 yards out and ten feet down, and I hit the 11 ring. My 20 yard pin was well over the target's back. Don't ask me to explain how it works or why, I just know that I walked away with an 11 on that target. Would I try it in a tree stand with a monster rack right below me? No, I would wait for a broadside shot to present itself before I would shoot nearly straight down on any deer.
Climb a tree, stand on your garage or on a elevated platform and try it, you may be surprised at your results.
