In the "pure sh*t shot" category I once dropped a flying crow at 70 paced yards with a Remington M12 .22. The blood trail over 50 feet of fresh snow that ended at the dead bird (no tracks, just blood splatter) was all the proof needed for my witness to stop calling me a liar! (40 years later I still wish he hadn't turned to take a leak before I fired so he would've eyewitnessed the shot!) I never tried repeating the stunt.
