Just heard a story on the radio about a hunting "accident" in Wyandot county Ohio, in which a 12 year old boy collapsed and subsequently died after firing a 410 shotgun at a deer with his dad nearby. Supposedly the recoil of the shotgun caused his heart to stop according to a doctor. Something about a trauma when the heart nerves are repolarising during the heartbeat cycle can cause a rare heart failure. I would link the story but not sure how to transfer the link to here. It is on the WTVN.com website if anyone cares to read it. So maybe giving high recoiling guns to kids to shoot is not such a good idea? But you would think a 410 would be pretty light?
