Ultimately found that at least a full inch of throat/barrel was burned out. I can't imagine the circumstances under which a soldier would fire so fast to cause that to happen, until I think about what happened on the Russian front. Anyway, you might want to confirm just how much "jump" you're dealing with in the chamber.
