Does anyone know what might be the white, chalky substance that appears at the juncture of my 4 5/8 barrel and top strap every time I fire my Ruger Super Blackhawk? -Blued.
The gun has been purchased new. I'm only firing factory ammunition in it.
The occurence seems to be heat related; when I fire three or full cylinders or more I notice a small deposit of the stuff. It will not wipe off with a solvent soaked cleaning patch. I scrape it off with a knife blade. It sort of chips off.
My guess is that it is a thread compound from the factory, and that the heat of firing causes expansion and it is extruded out onto the barrel top.
