I have been powder coating cast bullets for a couple of years now and have had pretty good luck. With exception of the .40 s&w and 9mm I have to apply two coats of pc to keep from getting barrel leading. Is anyone else having similar results? Getting the same thing with multiple pistols the 9s are s&w m&P and glock 17 both slugged at .355 sizing to .357. the 40 is a s&w 2.0 slugged .4005 sized to .402. My alloy is running around 12-13 bhn pc is eastwood ford light blue and pbtp clear.
