As far as stopping them goes, it's always a gamble.
In Dan's instance when they're close like that volume is so critical and tough to predict.
Too soft and the buck doesn't stop and he blows his shot opportunity.
( I don't know about everyone else but if I plan on a walking shot, i can concentrate on a walking shot and execute, I can't mouth grunt and still get a shot off effectively if the deer doesn't stop.Too much to do in a split second)
Too loud and the buck spooks, so its always a gamble.
I've done both on shots like that and had both senarios happen.
Now as far as Dan's comment on the longer shots, that's no gimme either...
Had it happen yesterday morning on a big 8 at 27yds. I stopped him as he went through my last spot i could shoot. I touched it off and watched the arrow fly right over his back.
It coulda been me but man the shot felt really good so idk what the heck happened. how much he ducked i'll never know cause i don't film, coulda been an inch coulda been a foot?? All i know is he had the last laugh.
For now...
