So which load data do we use for plated bullets? Lead or jacketed? I assume lead, but inquiring minds...

I used same as jacketed. Don’t like them. They are softer than jacketed.
I ran into the same thing with my 686 and extreme 158 gr TMJ-HPs. I get a lot of unburned powder and velocities are taking a wild swing. There's not much of a crimp groove on the Extreme bullet. I've tried the Lee Collet crimp die and a taper crimp die but still get wide velocity swings, unburned powder and dismal accuracy. My velocities' were in the low 1000s range and about 1.4 grains below max for 2400 powder in Starline mag cases.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.
