I just got a few Winchester #12 all brass shotshells, mostly for historical reasons, and to go with an old double my wife just inherited. I thought it would be fun to try to reload a few of them, but cannot find any recipes. Are there any out there? Obviously I wouldn't want to do a lot of reloading with them. That is what AAs are for.

I would suggest that you post this question in the Casting forum. I'll bet some of the new guys will have an answer for you! derf
