Barrel cleaning question

[JMPhoto]

I just purchased a brand new Browning citori. I cleaned the barrels with a couple patches and hoppes #9 before shooting to remove the goopy metal protection they put in from the factory. I shot about 50 rounds over the weekend and then cleaned it last night. I was surprised when the patches started coming out with some shiny flakes on them. It was hard to tell if they were lead, powder flakes or what. I got paranoid and thought something was breaking apart inside the barrel. I had to run the bronze brush through many times and several patches with CLP and it seems to be gone now. I never noticed this before on any other shotguns. I am assuming nothing is wrong with the barrel since it looks nice and polished inside. I don't have a bore scope, I just hold it up to the light. I was shooting remington Nitro sporting clays 7.5 12g. Anybody ever see this before?

the gun is fine. your shells are leaving the residue. don't know the specifics of your ammo but it was unburned powder or buffer flakes.

If they're little round flakes, that is unburned gun powder - nothing to worry about

Thanks. I just got really paranoid when I saw shiny (what looked to be metal) flakes on the cleaning patches of a brand new gun. I just never really noticed that before on previous shotguns.
