Winchester Super AA

Maxx424
I have been offered some free Winchester Super AA. I'm sure it is a shotgun powder so I was thinking that it may be able to be used for .45acp or 9mm. Took a fast look in Lymans last night and they don't even list it. Anyone know anything about this powder?

    It's a fairly recent powder. I didn't look to see if they have any handgun data for it yet. Based on how they list it (apparently by burn rate), it falls between WST and WSF. If so - and that's an assumed if - you ought to be able to use WST data and get slightly lower pressures and velocities using Super Handicap. That's what I'd do.
