DESTRUCTIVE LOAD PRESSURE DATA!!!

THESE LOADS EXCEED SAAMI SPECS. THEY ARE INTENDED TO RESULT IN
CATASTROPHIC FAILURE OF THE FIREARM AND/OR THE RELOADED COMPONENTS AS
A MEANS TOWARD COMPILING LOAD PRESSURE DATA. [/B]

I have calculated the results.

Hodgdon: 38 Super 1.265", 135 gr FMJ, 12.8 gr LIL'GUN, 32,400 cup, and 1357 fps.

I calculate: 9mm 1.169" 130 gr FMJ, 13.8 gr LIL'GUN, 44,000 cup, and 1538 fps.

I used the ratios from Lee's "Modern Reloading":
1) If a bullet gets 10% then the velocity looses 4% and the pressure gains 8%.
2) If powder gains 10%, then the velocity gains 8%, and the pressure 20%.
3) If the powder space goes up 10% then the velocity looses 4% and the pressure looses 13%.
