"The Hornady 500 grain RN bullet can be driven to a MV of 1700 fps by 50.1 grains of IMR 3031, and 1800 fps by 53.1 grains of IMR 3031."

I was wondering if IMR3031 wouldn't be a good propellant for the old warhorse. I found it about the best (though very slightly on the hot side) for 150 grain jacketed loads in a 30-06. I use about 50 grains there also.
