I just did a quick cross-check between #6 and #7. They expanded the 300 SAUM data to 10 powders per bullet weight (4 per in #6). The 7mm, however, they actually reduced to three powders per bullet and the ones still listed appear to be copies from #6. It appears AA3100 powder was removed from the 7mm SAUM listings.
AA3100 is listed in the new guide as being a "discontinued" powder. Ref. pg. 71
