So I neglected my shotgun. Its a old beater mossberg 500 with a field barrel I got in trade and have had for a while and just shot it. I had an issue the other day and decided to get it together. The gun is fully cleaned cleaned, oiled, and back up and running but I'm having trouble getting the barrel clean. I tried my mainstays, Bore tech elimilator, bore tech carbon, weapon shield CLP, Lucas extreme duty and I still have a funky looking spot about half way down the barrel. My understanding is shotguns have some weird fouling due to the plastic wadding.
What do you use / what would you recommend to clean the barrel?
