I am a bit confused about your information. In you OP you state that you are firing your 9MM Luger with some of your reloads. Then later in this thread, you state that your 9mm reloads are loaded with 90gr .309in. Hornady HP bullets behind 5.0gr of Bulleye powder.
Hornaday 90gr .309 bullets are designed for 30 Luger brass, and would be too small in diameter for 9mm brass. They would just drop into a 9mm brass case.
So were you firing 9mm, or 30 Luger handguns, and what was your load.
