I've seen a few:
- Longest shot on an elk, 720yds. Right near the top of a mountain, I was shooting from 1000ft below. Hit him well and he dropped at the shot, then slid 400yds downhill on the snow. Ended up only 50 yds from another hunter who had shot the larger herd bull before me at close range (so I'd shot safely, he was a quarter mile from my bull when I shot it). Guy was awfully surprised an hour later when I climbed up to my bull, he had no idea it had been shot.
- Shot a doe with a muzzleloader at ~150yds in unusually heavy early snow. It ran to a ditch and tried to cross but couldn't get out, died in the bottom. I got down to it and darn near got myself stuck down there, took 15min to get myself out in the heavy snow, drifts, and steep banks. Came back with a snowmobile, rope, and second person to extract it safely.
- Shot a nice buck with a muzzleloader down a corn row, clipped a corn stalk and hit the deer low in the leg. Tracked him a quarter mile, he crossed a pond for no reason. Tracked another 2 miles, jumping him with increasing frequency. Finally caught up to him neck deep in another pond contemplating the swim. He went for it so I shot him again, had to wade in waist deep to pull him out.
