WC844 is different from WC846 only on an "As-built" basis, the recipe is the same. WC846 you call Bl-c(2). The original patented recipie comes from the 30's, and Olin doesn't make it anymore anyway, so don't think they are all that different.
As for the "Sensitive" issue, Denton did tests with H335 against Varget, and H335 was much more stable. So don't get to wound-up about theory of it all. MOST of the stability "problems" that powders take the blame for, come from people cooking them in chambers(or freezing).
Also don't think that QuickLoad can tell you what is happening. Hartmut really struggles to accurately describe how any ball powder out of General Dynamic's Florida plant.
