Should really look into trailboss powder. Will put your right around 800 to 900 fps depending on charge with a 240 cast. No short case in the cylinder. Full case of powder. Can use less expensive and typically more readily available brass. I have become a big fan of Trailboss in a wide range of cartridges.

Tip on anything LEE. Try Titan Reloading. They are basically the unofficial LEE factory store. Located just a couple miles from LEE. Better prices than LEE and typically stock more than LEE. Good people to work with.
