I have a lot of bullets for my .357 mag that I don't shoot that often, so I'm considering trying them in my 9mm. They are RMR 130gr FMJ and MBC 140gr Cowboy 14, BHN 12. I think I'll use 147gr data for the 140gr bullets and work back up with HS-6. 4.8gr of it works great with MBC 147s for me. What about the 130gr? Would you use 125 or 147gr data?
I'm going to try Longshot, but I only have jacketed data from Hodgdon. Does anyone have good load data for a MBC 147gr with Longshot?
