45 Colt with Sierra Sports Master 240 Grain JHP

Lee

Six Pointer
I’ve been given a couple of boxes of the Sierra’s and I’m looking for recommendations on standard pressure loads. They will be fired in either a Ruger Blackhawk, Redhawk or 45 Colt rifles. I have more types of powder than I want to admit to; if anyone has a load that’s worked for them I’ll try it. Feedback on the bullet’s expansion would also be greatly appreciated.

My standard 45 Colt load for the last five years has been Hornady XTP’s over Hodgdon H110 so I am not looking for a “Ruger Only” high pressure type load. 800 to 950 feet per second would be plenty of power and more importantly accurate, I hope.

Thanks!
