2 questions concerning the 257 Wby Mag

First (since all my books are still hidden in storage) I find NO starting load for IMR 7828 on Hodgdon's site. Recommended starting and max loads would be appreciated, along with recommended loads with this powder. (Buddy already bought it)

Second as he discovered he wound up with 1 pound of 7828, and another of 7828SSC - is there a difference in data between them?

Thanks in advance - Mark
