Anybody read about this. I don't remember the place, but somewhere in the south. This retired driver had become a civil war relic collector, had been going out digging up bullets etc. He had an old civil war cannonball that he was restoring and it exploded very powerful shrapnel went like almost a mile away. I didn't know those things exploded, I thought they were just balls of lead or iron that were propelled by gunpowder.
