Need some Barnes manual data

I'm in the process of working up a .257 Wby. mag load and need some data out of a Barnes manual. What is the max. loads for 100 grain XLC's using IMR-4350 and IMR-7828? I will back off from the max. but I need to know where the max. is at.
I'm getting 3700 fps out of 71.5 gr. of RL-22 (27 inch tube) but want to see how the other powders will shoot.

Thanks,
Jeff
