30 years ago I settled on 8.5gr of Unique or 8gr. of 231 with Lyman 429421 cast from wheel weights as my everyday load. These loads are good for 900fps in my 6 inch M29-2. Powerful enough to punch through the chest of Black Bears and pleasant to shoot all afternoon. Load was passed on to me from FrankV who is as good a sixgunner you could hope to meet and knows his way around a loading bench. Good Luck
