My longest one shot kill was a feral dog running a fawn down while I was chuck hunting, it was on a dead run about 200 yards. I was shooting a .22 hornet. My longest one shot kill with a shotgun slug was a spine shot on a wounded running whitetail at about 80 yards, the best part was the slug shot a 1 1/2 inch thick tree limb clean off on its way to the deer. I did this with an old bolt action 12 gauge jc higgins with an ace of spades glued on as a rear site, ugly but effective! My longest one shot kill with birdshot was on a crow at 45- 50 yards 2 3/4 inch #4 20 gauge. My all-time best shot was the first shot I ever took with any gun. My cousin handed me a daisy red rider, showed me how to use it and told me to shoot at something. About that time a bumblebee landed on a limb about 15 feet away I took aim and ..you guessed it knocked dead off the limb. He asked what I was shooting at and I told him but he didn' t believe me until I walked over and picked it up and he' s been trying to out do me ever since! That was my introduction to shooting.
