No help for you with the load, but as an interesting coincidence...

The current issue of The Varmint Hunter magazine has an interesting test on bullet BC's, using G1 and G7 ratings. In the article, most of the Nosler bullets ACTUAL BC's are quite a bit lower than what they are rated at. Everyone has some on both sides of the line, but Nosler, especially the partitions; are WAY over stated.
