Yes, he was getting a slight crud of sorts but a wet swab of isopropyl alcohol and car windshield washer fluid took it right out. Like you, I shoot Goex most all the time. I just bought some Pinnacle again, and some Pyrodex P and even some Triple Se7en.. but 98% of my shooting is with good old Goex. When something is not broke then there is no need to fix it...
