Does anyone reload for a revolver with a 6 1/2" barrell? I bought one yesterday to use in the Bullseye Big Bore League & wondered if I needed to change grains or powders between it & my semi auto loads. For now I'll be using 230 gr FMJ, But will probably change to a LSWC when I get some time to test & tune. That dosen't look like it will happen anytime soon, so I'll stick with the 230gr bullits. How much pressure change will the longer barrell make? Maby not much, I don't know.
