There is big difference. Please refrain from giving out bad information. PD does not make a plated bullet.

Q. What is the difference between a plated and a jacketed bullet?
The difference in a plated and jacketed bullet is the outer covering of copper. As the plated bullet name hints, the outer shell of copper is applied through a process of electroplating baths of usually cyanide chemicals. This plating process results in a thin outer coating of copper that is about .003”-.005” thick. The disadvantage of a plated bullet is the copper outer covering is soft so in turn it is a more delicate bullet. When reloading, greater care must be taken as to not dent or crack the outer copper shell. A plated bullet also has a velocity restriction, generally around 1,050-1,100FPS is the fastest you will want to push a plated bullet, any faster and the bullet will start to fragment when it exits the barrel. Plated bullets should be loaded to lead velocities.
The reason we make a jacketed bullet, is we only want to make the very best bullet available. Our bullet start out with a swaged lead core and then are mated with the solid copper jacket in another process that forms the jacket to the lead core by force. Our jackets are made out .014” stripping to give you the very best bullet. By using a true solid copper jacket we end up with finished product that is much more consistent, accurate, and can withstand any of the velocities of any handgun calibers including magnums.
