Well, first of all, it was only bird shot and it was at a distance. It doesn't go deep under the skin since it's such small shot. It was also a 28 gauge, much smaller load than a 12 gauge and not much bigger than a .410 gauge.
Not funny when you get that under your skin but not life threatening by a long shot. Not much worse than a load of rock salt (and that can't be pulled out)
The guy ought to be glad he wasn't deer hunting with the VP. A load of 00 buck shot would have been a different story.
