The advantage of the 45 WinMag is more or less moot, unless one has access to low cost factory ammo or already loads the 45 WinMag and has them on hand. In my case I already had some on hand for my T/C Contender so I loaded them up in moon clips and a way we went. These were loaded with a 255 SWC over a stiff charge of Blue Dot. I'd probably use the same load in a stout 45 Colt load. I was using Starline cases and since my revolver is cut for standard 1917 style clips, I had no trouble with the clips. As Mr. Taffin stated in his fine article, I could see carrying 6 45 Colt rounds in the gun and using moon clipped ammo for a fast reload, with either acp's or Win Mags. :mrgreen:
