Art,
Yup...plumb through the skull with an old Foster slug mind you...

Another incident at fish camp....I looked up from cooking dinner to see the butt of a 200 pound black bear above the gunwale of my freight canoe....he was rummaging for grub/fish.....my partner grabbed the 12 ga with Fosters and waited until the bear stood up in the bow and shot.....another friend says: "you missed as I saw the slug skip off the water"......about then we heard the last bawl of an expiring bear 20 feet from the canoe.....the slug had gone plumb through the rib cage and lungs and skipped across the lake for a half mile.....

The ribs of that bear were very similar in size to pork ribs from a rack of ribs at the local dining establishment....certainly not armor plated!
