I have a Remington 870 Police Magnum with a 20" bead sight, fixed imp. cyl., parkerized barrel. I love this gun and she has performed flawlessly. I took her out of the safe today after not shooting it for a while and noticed the chamber (only the portion where the shell sits) had surface rust in it. The bore however is shinny as ever. I cleaned her out with a standard 12 GA. brush, patches, and Hoppes #9. She is now smooth as ice and shinny however a tad bit stained (just the chamber). Two questions:
1. Will this affect performance? Did I mess her up? I am pretty gal darned sure it is just fine as this is one tuff puppy of a gun, however I thought I would ask because I am kind of a paranoid perfectionist and wanted to run it by you guys because you are all so knowledgeable. 2. Why did just the chamber have surface rust and not the bore? Is it chrome lined? Thanks guys, I appreciate your time and help! |
| Remington barrels are not chrome lined. Have you left rounds in the chamber for extended periods of time. Hand sweat on shells left in the chamber can cause the chamber to rust. Just take a shotgun jag and wrap 00 steel wool on it and put it in a drill with some oil. Have at it and your rust issue will be gone. |

Steel wool on a bore brush (10 ga works great) wrapped in some 0000 steel wool. Put the brush on a cleaning rod, insert into a power drill, put some oil on the brush, and blast away.
Keep pushing the brush back and forth in the chamber until the rust is gone. Apply some oil to a patch wrapped over your 12ga mop and pass it through the barrel. New patch and pass. New patch and pass. do this until the patch is clean. |

Modern plastic shells can allow a chamber to rust, but not the bore.
Old shells were made of waxed cardboard and the wax melted on the chamber and could actually protect it. Its common to see old guns that were used with paper shells with rusted bores but perfect chambers. Modern plastic shells burn all lube out of a chamber and may allow a chamber to rust, but modern powder and primers don't rust the bore as readily. As above, using a twist of 0000 steel wool on a worn bore brush will polish the bore and chamber nicely. DO NOT use this method to clean any kind of rifled bore, it'll ruin it. Smooth bores ONLY. Many shotgun shooters buy a special chamber brush on a short handle just to keep the chamber clean of carbon and plastic fouling. |
