FWIW, as long as your range will allow polymer coated lead bullets, I'd suggest using them over plated; both for accuracy and cost. Two loads that I've had great results in 38Spl are:
148gr. coated .358 DEWC from Missouri Bullet over 3.5gr. of W231/HP-38 for light target use (cuts paper-punch like holes)
158gr. coated .358 SWC from same over 4.8-4.9gr. of W231/HP-38 for heavy defensive use.
Loading for revolver is the similar as for loading for pistol, except for the crimp. For light loads; WC load as above, you won't need to crimp at all, just seat bullet to the highest crimp groove. The long bearing surface will be all you need. Heavier loads, like the 158gr. SWC above, you will want to place a firm roll crimp in the crimp groove to prevent bullet creep from the recoil. I usually test my loads by loading 2 cylinders full, keeping the sixth round the same for both cylinders. If that bullet doesn't move after firing 9-11 rounds, I'm GTG.
