Really? I always wonder what the story is with the gun torture tests that pull them out of mud or peanut butter or some other crazy substance, shake it off, work the action a couple times, and then empty a mag.? The poster here might've toasted his barrel by something as simple as overzealous lubrication. Yet a mud puddle poses no threat? When I bought my Mosin, I cleaned the cosmoline pretty well, but in no way did I think I could possibly pop the barrel by not perfectly removing all of it?
