EMAG Barrel gunk

[Gman63]

Just a question for everyone. I just got a new Emag and it came with the two piec J&J barrel. I checked it for bore match on the paint we use at our field and the fit is about perfect. The problem I am having is that after If I clean the barrel before the start of a game after about 3/4 of a hopper all of my shots go wicked crazy like I have a barrel break. When I take the barrel off to inspect it the inside has a bunch of crud deposited on the inside, I thought is was the paint but I tried a friends barrel and shoot about a half a case through it and it looked and shot fine. I tried Armeson pro barrel clean, rain-x and a few other polishes but it continues to act wierd. Anyone have any suggestions? Thanks

it's probably oil from the valve. If not then it might be moisture from the paint, some paintball shells are dry & some have an "oily" coating. could be a condensation from the compressed air expanding and the temperature/humidity outside. could be ectoplasm, who was the guy who owned the mag previously? is is possible that his spirit resides in your gun haunting your games and causing ball breaks leaving behind the "gunk" which is in reality ectoplasm..the tell tale marks of the supernatural?
