I would be careful with graphite as I understand it can act as a very fine abrasive. Since it is a form of carbon crystal lattice, its lubricity comes from its ability of its layers to shear from one another. This property remains even at excessively low temperatures. A good property if I didn't care about tolerances between mating surfaces. I wouldn't use it on the rails of a gun that I spent lots of money on. Synthetic motor oils have tremendous shear strength. There have been tests of engines using it, run the equivalent of a million miles, that when disassembled showed almost no wear. That would be where I'd put my money.
