Put me down for having used a toilet bowl wax gasket mixed in the ratio of three parts wax, two parts mutton tallow and one part Crisco. It works well as a wad lube for shotguns and as a patch lube. Not as good as Natural Lube 1000 but better than Old Zip. The guns were always cleaned after shooting with Ivory Soap and hot water and then oiled. I still had to wipe between shots, and so once I stumbled on NL1K I began using only that in my rifles. I have a supply of wads rolled in the wax mixture that I use in my smoothbores (which never did need wiping between loads). I heat water in a 3 lb can and melt the wax/tallow/Crisco together in a 1 lb can set in the hot water bath - ala double boiler.
The ring would have been purchased maybe 15 years ago and was initially used as a dubbing wax for fly tying - and it worked well for that, too. It was probably two years old and opened before I relegated it for a patch lube ingredient.
