Re: Copper Fouling?
I would have to say it is not broke in yet.
Try cleaning until it comes clean, and then shoot one round and clean for at least 10 rounds,
then shoot 3 shot groups and see how well/fast it cleans up.
You have nothing to lose and you may greatly improve the resistance to foul.
When proper break in is performed normally you begin to see/feel the improvements after
8 or 9 shots.
