For anyone that cares...

Seems the max load gives me the best accuracy in my XDm 9mm. They are running about 1020 FPS, so plenty fast for making minimum power factor in USPSA, and still slow enough that I don't feel a real heavy recoil. This was chrono'ed at about 10 to 15 feet in the shade, and the paper plate is at 25 yards. (Whatever the distance at bay 2 at Talon). Anyway for what it's worth, this is what I get.
