I don't have Quickload, or have ever seen actual psi pressure test data for these loadings, and am curious about this. Anyone ever see lab pressure data done for these/run, or can run Quickload for a decent guess to help out?
Standard Disclaimer: I want to know in the pursuit of knowledge, and have absolutely no intention of trying this data, or recommending anyone here do so. Obviously these loadings are WAAAAY above anything published by a propellant/bullet maker, and again are listed here as illustrative, in order to gain ballistic knowledge... I'm very happy to never exceed the 1200 fps+ I have gotten with published data for 124 grain jacketed bullets; just the same I'd like to learn more about these crazy major loads working pressures.
Here is the load data I found, and all it takes is googling "9mm major data", so it's not like it is any secret. The author of this data is Alan Meek, and I have listed the top charge weight for each select propellant with hi/low velocity in fps:
Barrel: Bar-Sto Precision Length: 4.25
Bullet 124 Jacketed Hollow Point Zero 0.355
Case: Winchester
COAL: 1.145
Powder Hodgdon Longshot
Charge High Low
7.4, 1396.8, 1377.4
Powder Vihtavuori N350
Charge High Low
7.3, 1402.0, 1363.3
Ramshot True Blue data
Charge High Low
8.0, 1398.0, 1382.0
