I have had very good luck with a mixture of approximately 1 part melted beeswax to 3 or 4 parts olive oil. By applying this mix generously on the cylinder pin, and sparingly where the rear of the cylinder rotates against the rear of the frame, I have gotten as many as 96 shots with no cleaning, and the cylinder still spun freely. Some days a few shots less, but not many. This was with Schutzen 3F and one eighth inch thick wads lubricated with the same lube seated under the balls. And all without the huge mess associated with having grease blasted all over the side of the frame after each shot when lube is applied over the chamber mouths.
