I just follow FMJ reloading guides and they have worked just fine for me what calber are you shooting. I have lots of data for 9mm 115g and 124g Frontier CMJ Bullets
I use the Frontier in 9mm. The Lee reloading manual has some loads for 'copper plated' which I've used. As well the Hodgdon 2008 Annual Manual states "For plated bullets such as the fine line of Berry's Bullets use existing lead data for the same weight bullet" which I have done as well
