Weekly wipe down cleaning/inspection-rust in the barrel?

    I do a weekly wipe down and inspection to avoid any corrosion. This week I just happened to look inside the tip of the barrel and noticed brown color in the groves.

    The barrel has less than 200 rounds through it and of course with non-corrosive ammunition. I seriously don’t think its rust since there are other parts of the barrel that are missing the coating and the metal is still shiny. Does HP use a coating in their barrels that turns brown? Thanks.

    I have not heard that one before?

    My guess would be copper fouling mixed with the residue from the powder in your ammo.

    I have noticed on some of mine that when I use some European ammo I get a brown residue when I clean and I know it is not rust. I do not get it when using US ammo. I wonder if it is something in the powder or primer.

    I got some of that in my SKS shooting cheap ass ammo. It might be some kind of filler they mix with the powder???? Can't remember what brand it was.

    I used 50 rds of Tula and about 150 rds of Wolf.

    Tula's some dirty assed ammo.
  8. Ain't that the truth! My Sig 938 doesn't like Tula very much - but my C9 eats it and doesn't complain at all.

    It's copper fouling

    I had the same issue with my JCP 40 - medium brown residue in the grooves. It took about 10 passes with a brass (not nylon) bore brush plus several pads soaked with Hoppes No. 9 to remove it all. It doesn't create an accuracy issue unless it builds to a ridiculous level.

    Thanks, I will try that. Would running domestic ammunition fix it too?

    Copper fouling

    If memory serves, it was a result of using domestic ammo, either WWB or Remington. I haven't shot any steel cased ammo through it, although I have a lot of the stuff.
