Just for what it's worth, I bought some of the plated bullets for .30 carbine and tried them with the same load I used for regular jacketed bullets, 14.0 gr of H-110. That should be around 2000fps, and they worked fine, accuracy was good. Bullets recovered from shooting into sand filled tires, showed they held the rifling well, and no exposed lead. Seems the plating held up fine, even at 2-300 FPS above their "rated" velocity. Haven't shot enough to see if there's any different amount of copper fouling than regular jacketed.
