Back then, I experimented a lot with powders...Hercules 2400 seemed to burn cleanest in stainless pistols (AutoMag; Casull; Coonan; Ruger 44); and with 20grs to a shell, it shot pretty well...
I've been trying to order Win 231 through my local dealers for a couple months now; they've been unable to get it...(I use 231 for my 9mm and 7.65/7.63 loads)...
Might try Accurate Arms #7 or Hodgdon HS6 for my 9mm/7.6x loads if the Winchester powder is unavailable...
With the regs pertaining to hazardous material, it almost costs as much to have 1# powder shipped as it does to buy it...
Back when I had my AutoMag, there was a newsletter you could subscribe to that had a lot of articles about the AutoMag; reloading was a popular topic. I don't recall who started it, but he was a well known collector and is probably still around...(I included all my copies of the newsletter with the pistol when it was sold)...Little tidbits on what surfaces to polish; best lube for maintenance (I used LSA); articles about the electron-beam welding used to attach the barrel ribs...
Very interesting pistol. Rotary bolt and all.
