Arkansas, no offense intended. A spine shot does mean that the arrow did not have to penetrate the "shield", and that particular area is not usually covered in 8" of fat. I wouldn't expect the arrow to shatter the spine and embed itself deep into a rock, but I would have expected for what would be considered "good penetration" to see the broadhead at least pass all the way through the spine.

I think your pictures are very educational to see what an average set up can do when a broadhead misses the mark and hits bone. If that had been a shoulder hit that boar would still be running around.

Congrats on a real good hog, and thanks for the pics. There is absolutely no reason to get fired up from my comments.
