[QUOTE="Rardoin, post: 1966042, member: 114954"] You are correct. The grey dust that coats your fingers after handling smokeless powder is indeed graphite. It is added to improve handling characteristics/reduce clumping. I can't find the information at present but I did read a document prepared by Alliant that mentions adding powdered graphite to powder containers if clumping of kernels is an issue. They even suggested a quantity which was on the order of 1/4tsp/lb IIRC. The small amount inside the case after dipping/swabbing necks is of no consequence. I have lubed with Imperial graphite using the ceramic ball kit. I have also lubed necks prior to mandrel expanding by dipping the neck in Hornady 1 shot (sprayed in a small cap to pool the liquid). I wipe the lube off the neck exterior but leave it in the interior as a seating lube. It is lanolin and does not affect combustion at all. It is my preferred neck lube for competition rounds as I can feel/read seating pressures better than with graphite lube but for hunting rounds I use graphite. [/QUOTE]
