Actually, you are the person who is guilty here of putting out false statements, not the Register Guard.   Have you never seen any of the trick shots videos of  legendary marksman Tom Knapp shooting his 12 gauge Benelli at exploding tannerite targets??   Do an Internet search, and you will see him doing it in many of his videos.

And there are now low velocity versions of Tannerite that shotgun shells can easily detonate.
