I have a 1976 blue one that I have shot many times with BP. Now I have an R&D conversion for it and was wondering if the .45 Auto Rim could be used in the cylinder? Opinions?
Thank you for the replies. The reason I ask is that I would like to use the ROA for shooting ISU matches. I started shooting these matches in the early 70s with a Blackhawk and later sold off the Ruger (my mistake) for a 1911 that I built into a race gun. Now I want to go back to the long sight radius of the Ruger. The rub is our indoor range doesn't allow BP shot. That is why I was thinking about a shorter case loaded more like my .45 ACP, which gets 4.1 grains of Bullseye under a 200 grain SWC. What about trimming down .45 colt brass? would that work?Driftwood Johnson":d29atyj2 said:Howdy
No. 45 Colt rims are .060 thick. 45 AR rims are .090 thick. The cap will not close properly over 45 AR rims and the cylinder will not fit in the gun. You may or may not be able to chamber 45 Schofield rounds, they have rims the same thickness as a 45 Colt, but they are larger in diameter. I had to have the countebores in the R&D cylinders for my Remmies opened up a tad in order to shoot Schofields in them. But if you want a really short case you will be able to chamber 45 Cowboy Specials in your R&D cylinder.
