[QUOTE="Hugnot, post: 2704641, member: 115658"] No sarcasm intended - heavy black fouling & observed radial copper fouling in throat after only 30 rounds fired thru a new barrel would indicate a problem - rough surfaces - this should not happen. The barrel might have been chambered with a defective reamer. Those radial copper deposits are a big concern. Cleaning the barrel would remove any evidence that the event occurred. CA Ridgeline FFT might be able to polish out the rough areas - indicated by those radial copper deposits. The copper deposits are not evenly distributed meaning the throat/lands are not uniform. I don't believe in "carbon rings" - radial black deposits - yes. These I clean out with a bore foam cleaner, high surfactant motor oil & JB paste (diatomaceous abrasive). Carbon is inert but can be attacked by heat and that would damage a barrel. No, CA Ridgeline FFT, would not be on the "hook" for a carbon ring but would be on the "hook" for a substandard barrel/chamber job. Hornady might be asked about that lot of ammo. Stuff happens.
