Thanks for the info fellas. I must admit I was looking for a different answer. I worked my way down to 12 grs of H4905 if memory serves, but the report was still loud, and the primers looked funny. Even though the groups started tightening up a bit I didn't feel right about dropping the charge any further. I made the cases from 223 brass (for the first time) , and between that and the aforementioned stuff i quit.
