I never heard of that one. I was looking for a way to "clean up" a 7mm Mag. chamber in an Encore to and using the .348 case came to mind but was too short to work out. I sold the barrel but the idea of a .348 necked down and blow out stuck. I'm sure that something similar has been though of before though. A 7mm-.348AI kind of idea.
