rust
 

All of my hammerguns get rust in the left chamber and on the breech face just behind where the shell would hit or be. Not any on the right side. Not any of my hammerless guns. Three Parkers and two Remingtons do it so it's not a brand issue. I used to just run a bore snake through the barrels and then with a oiled patch run over the outside of the barrels and receiver and put them away. Now they're taken apart and the bores and breech face also oiled. I can't think of a reason why one let alone five different guns would do this. Any ideas ?

I had that problem with a VH after only a short time after shooting it. (Maybe 2-3 hours later after I got home). I now carry one of those TICO fuzzy sticks and before I place them in the gun draw I run it down the bores with a little oil sprayed into the chambers. I then wipe the breech face down and place them in a silicone gun sock or soft case with the sock. I can't explain why only your hammer guns do it but I'd be willing to bet that it has something to do with the surface texture of the metal (for the lack of a better term) and placing a warm gun into a cool environment causing condensation. The rougher surfaces would tend to attract debris which would attract moisture. Just a guess.

Paul,

This might sound weird but I am wondering if it is somehow the way you store the guns. Is it possible you store them horizontally so that oil you have in the chamber runs away from that area causing it to rust but the little bit of oil on the bottom part of the chamber causes that area to stay rust free. Just a thought but my guess is probably not.

I have the exact problem with my Parker Hammerguns. Left chamber and face only. I have tried several products, EEZOX and Q20, most recently as they are supposed to dry and leave an impenetrable film. I had used Ballistol previously.
This has happened when they are stored vertical and horizontal.

I have had the same problem. I hang my guns on the wall and have had this problem with the side closest to it. I stopped the problem by not oiling the after cleaning. I keep them clean and dry and lube them be for shooting them. this problem only happens on walls facing the exterior not on the interior. a slight temp. difference and some oils seem to attract moisture, that's my guess.

I clean my barrels with Kroil and have never seen a problem like this.

i use wd -40 and no problems with hammer guns or hammerless..some stand in a corner some in the tomb and some on the wall...charlie

Boy, I've heard some bad things about WD-40 as far as rust preventative. I use it all the time for other things but not to stop rusting. Anyways, the guns are stored vertical with muzzles down. It's nice to know others have had this problem- wonder if the chamber on the left side is a tad bigger allowing burnt powder to escape around it? Have to bring home from the club my dial indicator and check them. Mark, I save that can of Kroil you gave me for nasty stuff and use Rem Oil on the bores and breech face.

Is your shotgun effective out to 60 yards?
 

Puter acting up, was trying to put this in new thread.

First, WD-40 is one of the best products I know to prevent rust. Not so much for lubrication however. Secondly, the reason any gun metal oxidizes is improper cleaning after use. I've scrubbed my guns with Hoppes No. 9, bronze brush, and clean patches after every use and have never had a bit of rust.
"bore snakes" etc. and other quickie methods are NOT cleaning a gun.
Finally, priming might be a culprit. If you are using import primers, try switching to US make. However, I shoot thousands of Fiocchi and Nobel primers with no problems. I dislike Cheddites however.
