I usually shoot the 240 XTP out of my 7.5 Redhawk. It does a great job for me. However, I have a friend that wants me to shoot some of his reloads. They are a 250 LBT LFN bullet over 20 grains of WC820 with a Federal 150 primer. Does anyone have any idea what kind of muzzle velocity they would have and how they would perform, as compared to the XTP? I have never shot cast bullets from my 44. Thanks for any comments or ideas you might have.
