I had it once.
My first buck ever.
I was 16 and deer hunting in Utah and a spike wandered by.
I shot him, but he didn't go downright away.
I emptied my rifle and only hit him one other time (a grazing shot in the leg).
The first shot was fatal, but I was shaking uncontrollably after the first shot........ By the time I reloaded he was dead.
Never really had it since. Still love to hunt. Still get excited. But that time I just plain lost it and was shaking like a leaf.
