RE: FAST??
To be totally honest, Gary - I think I may have blew through shoulder blade on Buck #2 this year. He was quartering-toward a little, and I hit a little forward and high entry. I never skinned him to see, but if I didn't hit the shoulderblade, I was close.
Smashed something pretty hard, b/c I heard it hit hard and the arrow was barely sticking in the ground.
The first deer was clean rib punchthrough - and it was buried 4" deep in the mud, far side.
