Yep, we're into the gray areas of reloading again. This is why i don't rely on primer charts, they're not reliable.
As for burn rate charts, a spread of 4 powders is negligible, some of the powders within a range of 7-8 are so close in burn rate that some testing procedures will vary the results. Now if one had a powder listed at lets say #8 and another chart had the same powder listed at #48, then I'd begin to worry. If one is at 6 in one and 10 on the other, I don't think it's a big concern; it's verified to be within the top 10% of the fastest burning powders, so one can reliably predict that it can be used well in loads requiring such.
I'm going to have to look into the 700x though, that spread does seem a bit much. I'll have to try to find the charts you both are looking at and see if they have a date on them. There may have been a formulation change or something else.
