Wish I could still buy Dixie GW Old Zip patch grease. It was sheep fat rendered , and shot best I've ever had. It was ok to use in winter hunting. I ruined some rendered liquid bear fat tying to make it a little thicker. Recipe said to thicken the liquid bear fat w/ some real bee's wax. Though I followed the instructions , I added too much bee's wax , causing the bear fat to be too thick.Could just barely lube patches in summer. Cool weather , the lube was too thick.
