Since we are snowed in today with a Snow Emergency Warning in Hood River, I finally got out to my shop and lit up my heater. I had two new friends waiting for me, a nice new box of Sierra 85 gr Round-nose soft-points, and a brand new jug of AA #9. I have never used either before, but when I bought my Lee dies the enclosed load data listed Old #9 as the ultimate best powder. Yeah, I know....faster isn't always better,.... bigger isn't better either but that's not what SHE said!
Ok, they claim 13.1 grs will deliver an awesome 1927 fps. I figured 13.0 will suffice, I haven't tried these loads yet, but I'll get back with a report.
