If you look at Alliant's Data you will see that BD is probably the safest powder to use in a 9MM as you run out of room in the case before you get excessive pressure. I don't think you could intentionally overload a 9MM with BD, there simply isn't room. I recommend you open that can of BD and get to loading.
