found this in a farm field. It is lead and almost a half an inch across, weighs a ton, would wreak obvious carnage passing through you. Where certain musket balls that big? Also you cant see it in the pic but there is a flattened ridge running around the ball as if there was a rough seam that was filed down or trimmed off if you will. Was that common practice? Otherwise Im thinking is this a marble or maybe a ball bearing, but why out of lead then? It is in an area documented for the Sullivan campaign having marched through along the river where the field was. Where the musket balls big then? Thanks for any input, CL
