Like any reloading the best charge is the lowest that will cycle the action.
Don't beat the gun to death.
The reloading challenge is to find the combination of bullet and powder that will do that with the greatest accuracy.

No sign of this on any of my Lugers. AA#7 is said to be a powder especially formulated for 9mm. it's originally an Israeli formulation. It is claimed that AA7 produces high velocities without excessive pressures. Thanks, Kiwi

The only problem I have with AA7 is the granules it leaves in a Luger's action. I have no such residue with CFE Pistol.

Hmmm....I have found AA7 to be exceptionally clean-burning. And your previous comment was correct ....I have been loading round-meplat FMJs. WW white box, even though round meplat, offered less reliable function. I measured these at 1.163"+ . I tried mag-tech 115 FMJ, which measured 1.155" and it offered much greater reliability. I have had best function with 1.155" to 1.160" COLs.
