For some reason those ringtail sharps are a bullet that a lot of folks wanna dig. I got into a batch of them at DIV 12 and all I knew them to be were sharps bullets. I had dug like 5 or 6 of them and when we were kinda show n tell with our pouches for the day, some of the guys saw those ringtails and everything else in the pouch became un-noticed. It was then that I found out that some of those guys had been hunting camps like that for years and still not found one. I don't think they are rare to find, but are one of those that folks like to see.
And I was told they are Confederate, although both sides did have 'em. Which kinda goes with the other stuff I found in that spot. Got several drop gardiners, large caliber roundballs, a brass ramrod holder from a very early rifle. And another guy dug 4 VA buttons up the hill about 30-40 yards from me, and my buddy dug a Block A there as well.
