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.
Three shots are not a "group"...they are a "few".
If the Bible is the literal, infallible, unerring word of God...where are all those witches I am supposed to kill?
