Your post brought back memoties of past kills my first deer a spike buck
I was a greenhorn and all I had heard was stick them so I laid down my 30-30 and got my knife and leaned over the deer when the blade started in his neck he kicked with his front legs picking me up and throwing me several yards I then shot him again.
I shot a big 9 point which dropped on me and i hit the spine with my compound he drug off on his front legs, when I got to him he charged me
and I ran a circle with him right behind me before I could get another arrow in him.
Another last year I spine shot a doe with my excal.and put another in her fast.
I'd say if it happens again a fast second shot.
