sounds like a waste.. it would be a very thin coating that would rub off quickly. Better to moly coat, or try some thinned out Alox bullut lube. One of those tiny Lee Alox bottles for 5-6 bucks will do many thousands of pellets I would imagine. Squirt it on and slowly tumble in a jewelers tumbler or something slow and with a soft side container (mine is rubber).
get a chrony and let us know the FPS difference before and after... Maybe you are on to something..
