Now that my P-Valley order was in the house, I wanted to test 3N37 with Berry's 147 grainers. Load data from the Lee Modern Reloading (2nd Edition) manual; exact confirmation from Lapua's website for VihtaVuori pistol parameters.
OAL = 1.145 <> VMD .40+ trickle on the Gemini20 (Great scale). 15 yards w/prescription shooting glasses

4.5g of VV-3N37
I thought I'd leave the red-dot @ home & use the Heine Straight-8 irons on the stock slide of my G-19. This minimum charge cycled the slide & softly ejected the brass. Minor recoil (for me) was easy to control.
4.7g of VV-3N37
Bumping up 0.2g, this selection finished slightly high with one laggard to port (probably me). Recoil felt fine
4.9g of VV-3N37
Now we're getting somewhere I liked the upper-band charge with the peppy brass eject. Tightening group indicated to me that it's close to ideal for me .
OK - Parabellum People: Don't give up on those 147 grain bullets just yet
