I think it may have been Ayoob who first came out with the warning, but I think I first encountered it a few years ago in Jan Libourel's column in Guns and Ammo. But I don't recall either man ever citing a specific case. I just went to http://www.ayoob.com/ and all I can find there is merchandise, books, and seminars.

When I hike I carry my 29-8 Mountain Gun featuring my own cast RCBS 250 grain Keith bullet. Let Mr. Prosecutor make of that what he wants. <img src="/images/graemlins/grin.gif" alt="" />
