Get yourself a #45 drill bit. They are used to insure/measure standard size flash holes. If the drill bit will not enter a S&B flash hole, drill it out with that drill bit. Unlike most, I like S&B 9MM brass...as does my Browning High Power. The only problem I have with S&B 9MM is that apparently, they do not provide empty brass for hand-loaders. We have to rely on scrounging one-fired or buying loaded ammo to get the cases.
Sometimes you get what you pay for, sometimes you only pay more for what you get.

If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill? (Exodus 22:18)
