Try www.hodgdon.com. They list data for their powders for the 6mmBR Remington (will work for Norma also).
Also pick up a copy of Modern Reloading Second Edition by Richard Lee. It has a couple pages full of loads for the 6BR for bullets from 55gr to 107gr.
Varget (if you can find any) will be one of your best friends in the 6BR.
