I was wondering where my pet loads are on the Richter scale - or the IPSIC scale?

I think they are a bit mild, but have no idea what it takes to make major or minor. I recall the power factor was weight x velocity, but forget the numbers.

I am thinking of 9mm, 38 spl, 357, 44 spl, 44 mag, 45 LC and 45 ACP.

if I am close to making major or minor, I can warm them up a bit.

Thanks.

Sorry to bother you guys. I should have just Googled this. Here is what I found. Major is now 170 or 160. Minor is 125.

Standard: Pistol must fit within a box just slightly larger than what would be required for a standard 1911 pistol without optics or comps; 170 major, 125 minor.

Production: Duty pistols of 9mm or larger caliber. The gun must be DA or DAO. Single stage triggers are not permitted and the trigger must pull 5 lb. or more; 125 major, no minor scoring.

Revolver: No optics or comps permitted; 170 major, 125 minor

Your list doesn't include Major loads with bullets lighter thab 158 gr.
Eg. 147, 135, 130, 124/125, 120, and 115
