Sevens - you have a short chamber in that Springfield? I load all my 9mm rounds to fit a Springfield XDm with a "short" distance to the lands. Fat bullets got to be shoved deeper.
OP - I found a good load, for my pistol, at 4.8 grains of Unique under 115 grain Berry's set at 1.120 inches. Grouped at less than 3/4" at 50 feet off sandbags.
You may not find that "magic" OAL where the bullet just comes in contact with the lands if you have an ample chamber coupled with the narrow profile of the Berry’s 115 grain bullet. I find I must do the OAL thing when I’m loading heavier 124 or 135 grain plated or cast bullets with wider “noses” (profiles).
