Just as a note:

using 357 brass a starting load of 2400 is around 11.4 grains of powder. w231 can be from 5.5 to 6.7 grains.

If you use the little 38 spl. brass the powder amount for the w231 powder can be as low as just 4.0 grs to a
38 +P load with 4.7 grs at 890fps in my 6" 686 revolver with a cci500 primer.

50 rounds of 357 brass with 2400 uses 570 grs of powder.
50 rounds of 38 brass with 4.0gr of 231 comes out to 200grs.

Have fun with that new revolver.
