Some of us, who cast our own, like to use tallow as one of the bullet lube ingredients for black powder cartridges. I have had success using mink and beef tallow but I prefer to use lamb tallow if possible. Sometimes it is a little hard to get hold of. I assume that because the seasons are reversed down under it is now starting to come on the market again. I just ordered several pails from these guys: http://www.grasslandbeef.com/Categories.bok?category=Grassland+Lamb
I've rendered out a bunch of lamb.. used on my boots and all slugs, to include capping the face of percussion revolver cylinders. good stuff
