A couple of buddies and me, decided to try buckskin patches about thirty years ago, in our trade guns. We precut some nice thin buckskin, and lubed them with melted tallow. We took them to the range and tried to work up a load. They were awful, they slung balls everywhere. We tried different lubes, different charges, and different sized balls, nothing worked. The recovered patches were stretched into the shape of a hotdog.
