Thanks all, your data is really close to:
-
Alliant web site:
http://www.alliantpowder.com/reloade...tid=25&bdid=30
Speer Gold Dot HP 115 grain <<<-- not plated like my Berrys
Minimum OAL(inches) 1.125
Bbl Length 4
Primer CCI 500
Powder Blue Dot
Charge Weight 8.5 grains
Velocity 1,258 FPS
Starting at 10% below the maximum charge = 7.7gr.
-
Lee 2nd 9mm p509
115gr XTP <<<-- not plated like my Berrys
Start 7.5, max 8.5
OAL: 1.125
Basically the same as Speer Gold Dots data
-
Lyman 49th 9mm p341:
115gr JHP <<<-- more in line w/ Berrys site recommendations for mid loads
Start 6.8gr, max 7.6+
OAL: 1.090
-
Their velocity numbers is a tad over the max per Berrys plated bullet label.
-
TimSr, you stated: Your minimum listed loads will still be absent vacant space and work excellent in 9mm.
-
So 10% below 7.6 is 6.8 which is Lymans start grain. Did you ever use the 6.8gr and was it compressed or did it have some space?
-
The OAL for Lymans is shorter (1.090) but my components aren't theirs.
-
Hodgdon's Reloading 2013 Annual Manual p77-34 has a good article for OAL on last papr p28 finished on p30. I was thinking of doing what they suggested. Basically start long and shorten it up a tad until the round falls freely into the barrel then see if it loads ok in the magazine.

Plz comment. Thanks again.
