First, I had never heard of Berry's Plated Bullets, but I looked it up and found out they dont recommend speeds over 1950 fps, for the 150 gr 30-30.

What is a plated bullet and why the reduced recommended speeds?

They are just a thin clad cast bullet. The plating helps with keeping the bore cleaner than uncoated lead. The plating isn't structural like on a jacketed bullet.
