Re: Ruger Old Army Conical Bullets - Problem
I shoot the Lee .456 taper base conical tumbled in Alox. The Triple 7 is a smokeless powder. Yes, it should cut a lead ring. Make sure you use pure lead for you bullets. The hard cast bullets can bend you center pin from leverage.
The Lee bullet 230 grs over 35 grs of T7 will give you 940 FPS from the 7.5" ROA. The ROA was designed by Ruger from the great Rogers & Spencer Revolver not the Remington. It has a larger cylinder boss and a better lever lock chamfered .457 chambers like the R&S. The ROA does not bind up like the Remington.
This one of my ROAs. This gun has the custom Ballistics Cylinder made from an F-85 landing gear. It also has a taller front sight to handle the 1,100 FPS loads.
