I'm moving next to 4.3 grains and if that works OK I think I'm going settle on it for all of my old 9mm's, but it's primarily for P.08 and P.38 shooter grade pistols.

This all requires quite a bit of testing. I am just mentioning it in case others are going down the same path.

Bob - standard reloading ladder is to start at minimum and work up,
but in addition to function check group size by bench firing several rounds and measure group size.

The spin imparted by rifling works like a kids top. A tight spin goes straight. a soft spin (low load) wanders. OTOH too much powder causes the projectile to skid over the lands and also lousy group.
Reloaders look for that sweet spot in the middle
