More to the point, the 7mm Mauser was out of military production by the turn of the century. If I'm not mistaken cordite was also well on it's way out. That bullet would be much older than WWII if that is all correct.As a young'n I pulled apart an old 7mm mauser round ( I'm guessing WWII era) and to my surprise it had cut up rubber tubing inside. It was very flammable!
I'm still waiting for Hodgdon Fusilli, or maybe an Alliant Gnochi line...
