With out knowing your knowledge of reloading...BECAREFUL WITH PISTOL POWDERS in rifles!!!! If you have experience with this, and know what your doing. PLEASE, no offence meant. Better to be safe than sorry.
This velocity is attainable with one of the SR powders or look in the LYMAN book for the reduced loads. Substituting a lead bullet load for a jacketed one, at these LO velocities is a recipe for disaster..PLEASE be careful.
