By no means do I want to sound like a millennial that always needs to find blame elsewhere but every now and then we have those head scratcher moments where a “sure kill” isn’t. We’ve all heard of deer that were literally double lunged and oddly survived etc. This buck just happens to have a scapula that’s an inch thick. That’s one where you put it there, hear the crack and go “huh, didn’t think I would have hit the leg bone in that location but I guess I did.”
On a 4.5 year old Canadian deer that’s gonna cause an arrow fits I don’t care what head you’re shooting.
I trapped a large male bobcat years ago that had a healed and funky shoulder and scapula. He was very fat and large for our area, so he'd gotten over it. But it was jacked up.
Wish I'd taken a picture, but it was before the days of digital :)
