I've shot several that were basically straight down from a tree stand, so less than 20' from muzzle to deer. Shot two with a bow at same distance.
I once shot two does at less than 5 yards from a short homemade ladder, about 20 seconds apart. They rolled, tumbled and flipped down the same path for about 20 yards and fell side by side. The 150 gr Solid Base made huge holes and they slung blood everywhere. It was gruesome. Blood dripping from the trees and vines..... like something from a movie.
I also shot a nice mature 8 point once, running straight at me while I was standing on the ground in the middle of his trail. I'm not sure to this day if I shouldered the rifle or shot from the hip, but when he landed, he was less than 10 ft from me......
