I found an interview where the Great One says:

"PMC 230-grain ball and PMC cases loaded with American Select... .45 was loaded to IDPA revolver minimums, which were a 120 power factor, and it is also legal for IRC competition. "

Link for context:

So, if I understand PF, that means he was loading a 230gr bullet at ~520fps to make 120 pf?

If so, I didn't know you could load a 45 ACP that light. I'd be worried about getting a bullet stuck in the barrel of the 4-5" barrel guns he competes with.
