Hi All, I am quite familiar with shooting BP in my cartridge rifles, but somebody just gave me a bunch of Pyrodex and some 777 to play with. Never used that, and my question is what sort of lube to use on the bullets? Should I stick with a BP specific lube, or will 50/50 or even Lee tumble lube work? I figured I'd ask before I made a mess of my rifle and had to pull down a bunch of ammo!
