We dig a good number of .69 Belgian minnie balls on the Yankee side (as in shot by Confederates) of Boatswain's Creek that cut through the Gaines Mill Battlefield just to the north of the Watt House. The area around the Watt house was over run by Hood's Texans and a large number of Georgia troops. Belgian bullets are prized collector pieces. They have a distinct three ring pattern and are usually a really dark grey lead. The ones I dug didn't get that chalky white patina on them that most Enfield and Springfield bullets do while in the ground. And while most .69s were smoothebores these bullets are conical in shape. If I figure how to get a good picture on here I'd post one so you could see. When you hold that chunk of lead in your hand it's easy to understand the carnage that one of those rounds could cause.
