Your a fabulous shot to have as you wrote above:
"a whitetail doe broke out of some logging slash and crossed just 50 meters or so in front of me. I flipped off the safety and scanned behind her, and sure enough, a nice buck was running right behind. So I swung the crosshairs along his body and touched off just as I swung ahead. Put a bullet behind his ear."
You shot a running buck behind it's ear as it ran at 50 meters!
