Hoping someone here can shed some light on my problem. My cva wolf's breech plug is the new style, the gun is stainless and I bought it new last year. My breech plug has been coming out dirty in the thread area, I have three plugs for it and they all do this now to varying degrees. I don't remember having that problem when I first got the gun. the plugs have all been sized to the gun and screwed all the way in as far as they will go, and still gets dirty threads.
