Rick, if the thickness are pretty consistent use some for patches. I've greased some up and used them in a couple of primitive matches. I've read accounts where buckskin was used back yonder and I got in some pretty good shots with it. Since it would be hard to get real consistency as far as thickness goes I probably wouldn't use it for precise target shooting goes, but it would be fine for silhouettes or hunting.
Are you going to the range Saturday? I'm going to try.
