Just load your w231 in the middle of jacketed data with this bullet and go shoot. If you want it hotter, You can go to 4.5gr (edge of +P). I shot a ton of these for minor power IDPA before they lowered the required PF.
If you want to load .357 with that bullet, I'd keep it down to 1100fps for best accuracy. Don't load plated bullets to MAX in magnums.
