To add to the above here’s a couple pics I took this evening while cutting that quarter up.
The inside of that above pictured joint.
And a groove cut in the edge of the socket on the bottom of the scapula by the first shot.
First shot scrambled lungs and I gave him the second when he acted like he was going to move out. After exploding the shoulder knuckle it punched a thumb sized hole through the top of the heart.
