The biggest reason I was asking was that it's hard to find any load data on copper plated. Berry's new 124gr HBRNTP (hollow base round nose thick plated) bullets can (according to their website) be pushed to 1450fps now instead of only 1200. I wasn't trying to get them this fast, I only wanted to increase powder and see if my groups tighten by comparing the speed increase to plated data.

I wasn't planning on going over max plated data but was wondering since these bullets supposedly have a thicker plating if I could approach max jacketed data safely.

I bought the new Lee load manual and it has copper plated load data but now in bullseye powder. But it is refreshing to see someone try to include plated bullets in their load manuals.
