My favorite deer hunting story:
Around 1995 or so, hunting with my in-laws on a dairy farm around Dodgeville, I sighted in on a small buck about 80 yards away. Had a perfect sight picture when my 30-06 went off. The bucked jumped about four feet in the air and took off running. I figured that if I couldn't shoot it, I'd have to chase it down and choke it instead. I was hot on it's trail, only about 50 yards behind it (and gaining on it, by the way) when it suddenly did a back flip and dropped like a rock. A second or so later I heard a shot and looked across to another small hill and there was my 70-year-old mother-in-law, about 225 yards, away with her old 250-3000 lever action. She took it out straight through the heart while it was at a full sprint (also with open sights).
I discovered that I had lost the screw to my rear sight and it was just flopping around on top of the receiver. Even though my in-laws have passed on since then, I'm still hearing about it.
I'm sure there are some better stories out there, but this one is mine.
