Yes, I think I see a consensus here that Silhouette data is appropriate for WAP powder.

But, please remember that both of those powders vary somewhat from lot-to-lot. And, since they are marketed with different names, the difference between the two powders is not subject to the SAAMI limitation on variability of burn rates among lots of powder with the same name. The rather large difference in the postions of WAP and Silhouette on various burn rate lists indicates to me that there can be much more difference than indicated by the data used in QuickLOAD.

So, please remember to start low and work-up carefully.
