Jim, shoot me a PM with your email address. I compiled some 300SAUM data for a friend a few years ago, and I'm sure I still have the PDFs around here somewhere, on one of these hard drives. Might take me a bit, but I'll keep looking. In the meantime, I do recall my friend uses Varget to good effect. PM me and I'll find that data.
