Winchester 12g featherweight load duplicate

[Madpyro]

Does anyone have a recipe to duplicate the Win. AA featherweight load? I need 7/8 oz (26gr) of #8 shot at about 1000 fps. I have a recipe but it uses WAA lite powder which is no longer available. Any suggestions for a replacement?

I like Clays and I use Win AA cases but e erything is right at 1200 my 11-87 Sporting Clys likes them.
Many many years ago I had a bunch of Bullseye powder I found load data in a issue of American Rifleman great stuff but dirty.

Can't help directly getting down to 1000 fps. But Alliant Extra-Lite would prolly be the closest powder.

Alliant lists down to 1150 fps in 7/8 and 1100 in 1 oz. That's where I'd start. Scale down from there.

I think there's a fast Vectan powder which would suffice as well.
