check out hodgdons youth loads for h4895 powder. it can safely be reduced in charge by up to 60% in any load it's listed for in the hodgdon annual manual.
this could make your big kickin, powerhouse, handcannon a real pussycat to shoot in off season practice.
i shoot it in my 15" 7-08 with full powerloads, and get 2800fps, and great accuracy with 120gr noslers. i havn't tried any reduced charges yet, but they sure look interesting.
hey dan, check out the 30-30 reduced charges with h4895. that could possibly be just the ticket for forming ackley improved cases with lighter powder charges. i may have to try some of those.
