I'm looking at loading data for Clays for revolver cartridges (38 spl/357 mag and 44 spl/44mag) for rifle and revolver. I like Clays in my 44 Spl., and I'm getting better results with metering now. Hodgdon publishes data for Clays in all of the above cartridges, so I'm thinking about buying it 8 lb cans now. I would like to be able to load both target and defensive loads for both revolver and rifle using the same powder and projectile. The projectiles I'm currently using are cast lead 12 BHN. Missouri Bullet company says they are for 44-40 or modern 44 special velocities. I assume they mean somewhere around 800-900 fps. Question 1: What happens if I drive them up to around 1200 fps and about 33k CUP? (top end for both 44 magnum and 357 magnum) Question 2: Is there a better hardness rating for my specified purpose? Should go to a harder alloy for the higher velocities?
