Fellas -
I suspect that this "recent find" may be a thread stemming from a discovery and recovery made several years ago. There was a digger who came across a magazine in the general vicinity of Vicksburg about 5 years back. Lots of yankee iron came out of the hole. Those projectiles have long since hit the marketplace.
Now, there may have been a more recent find, but the two stories are close enough to be the same event.
