I have not done this myself, but would also not be too quick to jump on someone that did. The variety of scenarios presented in the woods could lead to any number of improbable outcomes, especially when wanting to assure that you dispatch an wounded animal as quickly as possible before it gets out of sight/range.

As for whether I have seen it, has anyone watched the Monster Bucks video (can't remember which one) where Duncan Dobie is hunting a field along the Milk River (its a rifle hunt I believe) and he is watching a large buck that will easily make P&Y with plenty to spare. The deer beds down out of his line of sight, and another emerges an hour later with the rack at a different angle and he shoots it, and I believe it scored about 120. The narrator made light of what happened, which I believe is the right response in any similiar situation provided the hunter acted ethically and legally.
