Maybe this theory has a little something to it but I for one do not necesarilly agree. I have stopped many of deer by making a sound and I have seen them go down within eyesight (50 yds.). It also depends on where the shot placement was. If you double lung or heart shot a deer, it usually does not matter if you stopped it or not it will/should go down within sight.

As stated my "case study" was not very controlled and there is always exceptions. However you must remember a deer can cover hundreds of yards in amatter of seconds.

Early on I shot many a deer that I stopped with a mouth call rightthrough both lungs or right through the heart only to have them take off on a dead sprint right out of sight.

Quite the opposite started happening once I stopped "stopping them" with mouth calls. Even marginally hit deer: one lung, one lung and liver, etc...died within sight, and the ones with good hits on them dropped even closer.

Not all, but most, again there was always exceptions.

I think you missed the point! Both shots being the same, Double lung no heavy bone hit, an alert deer (one that just got a shot of adrenaline from you oinking at it, and it looking at you) will go farther than a deer that did not have a clue you were there. Yes both are still dead!
Add in thepossibility of string jumping, rushing the shot, or the chance of it just haulling a$$ when you oink at it, I just wont oink unless I got to!
