Thanks all who supported my original post https://www.thehighroad.org/index.php?threads/9mm-load-development.910108/#post-12401676.
Using much of your advice I returned to the range and chronographed and shot for accuracy. Here’s a photo of the target. Start at the very bottom, that’s just some 115 grain factory ammo for a control group.Please assess the six remaining targets, top to bottom. Numbers next to each target indicate the charge weight grains, labradar series number, muzzle velocity, and standard deviation.
I think the 5.4 charge produced the best group and SD; seems a no brainer to me. However, 5.3 grain is supposed to be the maximum charge, producing 1150 FPS, yet I’m still shy of maximum velocity.
Am I okay to lock in on 5.4 as my load and get the dust off the press (photo of my “ballistics laboratory” attached too)? What am I missing?
Reloading manual data photo included too.
CFE Pistol
124 grain X-Treme CPRN
1.150 OAL
.002 crimp
Dillon XL750
Redding NxGEN dies
CCI MAGNUM small pistol primer
85 degree temperature, calm
Bag rest
Glock 19 Gen 5
20 yard target
7 round groups
No pressure signs at primers
Brass tumbled in walnut media with nu-finish
Hornady case lube
Once shot random range brass
