I've had it happen even with a .50 ….
I shot a good buck several years back, 75-85 yards up a slight grade…. I was hunting from a chair type blind shooting a TC .50 percussion gun.
I aimed high (above the shoulder but below the spine) shooting off a mono pod , seated. The deer dropped like a rock!
I watched as he tried too stand , twice. The second time when his head hit the ground I smiled too myself .. thinking about what had just happened…
As I laid my rifle down and started too make my way out of the blind, I looked back at the deer and he was starting too stand up!
Which he did and disappeared into the deep hollow…
Two drops of blood and a little hair… I followed the trail(tracks) down into the deep hollow where there was so much disturbance to the leaves from other activities I could no longer determine what was what..
Grid searched the area, nothing..
I did have a buck show up on camera the next Fall with a spot on his right side ( which I shot into) with no hair….
I always thought the ball must have hit exactly where I aimed….. imagine that.
That quarter head on shot sometimes pays off..
This one I killed sitting in Flintlocksforme's folding stool! lol
Thanks for the help Brother!
