Loading for Short Chambered Damascus Barrels

[mobirdhunter]

I realize I'm probably asking about something old hat to most here, and probably discussed many times before, but I'm getting back into reloading and would like some help in finding authoritative information on loading shotshells for Damascus barreled guns. Are there any good books out there? Authoritative web sites? I'm also looking for good step-by-step information for cutting down shells for short chambered guns. I'm interested in loading for 12 gauge, but especially 16 and 10 gauge (2 7/8"). I have the standard loading books from about 15 years back. I have kept up with discussions and articles about shooting Damascus guns, and have been shooting RST and Polywad shells for years. I have some load suggestions from good folks from this forum also, but I'm looking for a basic book that focuses on loading for Damascus, including Bismuth, Nice Shot, etc. as well as lead.

Is there there such a "creature" out there?

Thanks!
