No PF for SASS, in fact they often use cream of wheat to top off the small charges in those big cases.
No need to cycle any action - your thumb does that - so as long as the bullet makes it to the target you're good.
I didn’t think they had a power factor. We had a guy sneak into a IDPA match shooting a .38 revolver using squibs. It was ridiculous.
SASS should also get rid of that two hand hold for all their classifications instead of just “Duelists”. I never have seen a Remington or Russell painting where they needed two hands. Just saying.
