My best shots are the one-shot DRT kills, but my luckiest shot has a bit of a story.
I was hunting with a bunch of country boys, their dads, and my father-in-law. There were 7 of us in total. The younger guys were calling me "slick" since I'm a city slicker and were poking fun at my high tech gear, asking how much it cost and just busting my chops in general. We get to the field we want to spot, and there's a nice buck just on the edge of it, not 80 meters away. They all start firing, bang, bang, bang. The buck doesn't run away from us, but straight across us (no more than 50m at this point) and keeps going, full tilt. I cycle the bolt on my Weatherby, gun comes up onto my shooting stick. Everyone else is either still shooting or already empty. Deer is now ~250m away, well past us and moving quickly. Crosshairs on the bobbing tail. Bring it up just a few clicks... breathe out... load up the trigger... deer crosses the 350 mark... KABOOOOOOOM! 180 grain Nosler partition slammed into the neck just an inch below the skull, deer hits the ground so fast if you blinked you missed it. Paced it out at 386 meters.
The best part was I left the muzzle break on it and was the only one wearing hearing protection (of course they made fun of my high tech electronic ear plugs up until that point), the shot was still ringing out when I slung the rifle and started walking towards my kill. The others were in shock from the seeming ease of the shot, concussion of the noise, and the fact that it was the only round I bothered to feed into the rifle. "Slick" is now a legend with those guys, don't see them often and don't have the heart to tell them a target moving dead away from you isn't hard to hit when you practice to 600 meters
Doesn't help that the first time we went out to bust some hand-launched clays, I never missed a shot (3 rounds of trap the day before). I'm in my 40's now and don't think I'm going to bother them with the truth, just take those ones to the grave and let the legend live on!
