Hi to all. I too lost all my threads after the site’s update, so it’s my first response here. Sweet Old Bill, I don’t know what kind of rifle you own. If it’s something you value, I wouldn’t recommend using surplus ammo with it too often. Some surplus ammo can cause serious problems to weapons, especially to the autoloaders. These problems have been associated with a lacquer coating (for longer shelf life) found on some of the milsurp stuff. This coating, when heated under firing conditions, briefly liquefies and flows into the microscopic pores in the steel in the rifle's chamber. This fills the chamber slightly with the lacquer that solidifies into a nearly impenetrable build-up. Over time, the chamber’s ID is reduced and cases begin to stick.
