Plated bullets are to eliminate bore leading and airborne lead in indoor ranges. Most plated bullets have a thin plating that will strip when driven much over 1200 fps. For reloading, most plated bullet manufacturers recommend using data for hard cast lead. I have had good results with plated bullets in 9x19mm and 45 ACP, not so good results with reduced velocity 357 Magnum loads.
