Prevailing wisdom is to use cast bullet loading powder charges when loading plated bullets.
Gold Dots are actually plated, but plated thicker than Berry's or Ranier so they act like jacketed bullets. Speer is now making plated rifle bullets. The plating is even thicker to withstand the higher pressures/velocities/stresses of rifle cartridges.
As long as you are reasonable with your loads, plated bullets are fine.
