Was testing some reload’s this week.
Found a nice reload equation for Winchester 231.
Running 4.9 Grains on a 115 jacketed Bullet 9mm.
Runs great and is good out to 50 meters accurately.
OAL- 1.125
should be around 25,300 CUP

There’s a lot of variety of 9mm.
Dies, case manufacturers, barrel chambers, 'etc.
It pays to remember this when a recommended load doesn’t work out as expected…
Just a thought.
With a previous 9mm pistol, I found that the best load was oddly using dies for .38 super and 147 truncated cone bullets.
Go figure, but that was only after a lot of experimentation.
And always use a chronograph just for the sake of safely.
