Thread: Bolt Corrosion/ Pitting??

  1. #1

    Question Bolt Corrosion/ Pitting??

    Hi All,

    Pretty new to here, so apologies if this has been covered before, but my old stalking rifle is starting to pick up some black pitting on the bolt (see pictures). Is this normal? Is there anyway to clean it up?

    Any help gratefully appreciated!

    Tom

    No, it's not normal on a well maintained rifle, I've seen Mauser rifles and "Mauser Patents" rifles...think the British Pattern 14...that are now a hundred years old others from WWII and the extractor is as good as the day it was made. Save for loss of blue.

    Pitting is loss of metal caused by failing to remove rust. So under that rust the metal is attacked. That metal, now gone, is gone for good. "You failed to maintain your weapon"...as they say. However it won't affect how it shoots.

    This is perhaps too many folk on here "boasting" about how they only clean their rifle once a year or such and so. Mine gets cleaned every outing regardless of if it's fired a round and the exterior surfaces wiped with an oily cloth.

    I am sorry if it's "tough love" but it's down to poor maintenance at some point in its life. Either a previous owner or its current owner. Only you know who the culprit is.

    With too much oil that would have not happened. No oil... not a good idea. I never understand how people can suggest steel on steel should run dry.

    I don't bother with any complex and in-depth bore cleaning regime, all mine get is a pull through with a boresnake. You're quite right about the need to keep exterior metal in decent condition though
    A Man should be wise, but never too wise. He who does not know his fate in advance is free of care

    I don't either WS. As with you I can't see the benefit.

    A run through ten or so strokes with a oil soaked phosphor bronze brush then a swab out with a piece of 4x2 on a brass jag. And then a run through to oil the bore with either a clean patch moistened with oil or, if I have one, a nylon bristle brush. I used to use Edna Parker's "AC Oil" but I've about used all that up.

    So now I've gone to "Young's .303" (that I've never much liked) and KG4. I never leave "Young's .303" in the bore as it is a water attractant. Hence the KG4.

    Then a wipe over the outside metal with an oily rag.

    Ah! I'd forgotten about that one. Mind only because "AC Oil" was far better. But, yes, I'll look into that again. Thank you.

    After a rainy outing I flush the bolt either with wd40 or similar, wipe down air blow off excess and spray with teflon grease from a spray can. smear all over the bolt except the bolt face. I then wipe off and leave a thin layer grease on the body a bit more on the cam and lugs. I prefer too much grease vs too little. Then again we have a very wet climate. I do not entertain a deer hunting rifle that shoots over 1/2" unless it's an open sight bush gun. Grease, oil on the bolt does no harm to accuracy.
    I have a 1909 Argentino Mauser that doesn't have a single bit of pitting. (The previous owners cared for it well)

    A mate of mine had a Brno where the bolt looked even worse than that, as a previous owner had stored the bolt in a cheap leather bolt holster (looked like some Spanish tourist crap). The rest of the rifle was like new though.

    Any thing that holds moisture against the surface will cause putting sooner or latter. Anything is salty or corrosive will cause pitting even quicker. A quick patch down the barrel and wipe over with an oily cloth takes little time and also allows you to check over the rifle before using it again. Nothing worse than finding a screw loose at 4am on a dark morning when you take out of the slip in a muddy field!
