8.0 grains of 231 is a great load. I use that one a lot in my .44 mags. Standard primer and any bullet of 240-250 grains in weight works well. It works well with either cast or jacketed bullets too. It runs about 900-975 fps depending on barrel length. 8.5-9.5 grains of Unique is another one, using the same bullet weights. About the same velocity, again depending on barrel length used.
