Was "talking" (PM) with a another THR member about Silhouette. Looking it up on burn rate charts (which of course are closed bomb tests and not necessarily how a powder behaves when loaded in ammo) we found some interesting things. Some charts show it fairly fast around Green Dot, others show it quite a bit slower. Ramshot who makes it puts it around Green Dot (faster than Unique) but Grafs and Hodgdon put it slower around Autocomp of CFE-P. I have seen other charts that show it around Green dot as well. I tend to agree with Grafs and Hodgdon for the small amount of testing I have done with it. Would be interested in hearing from others who have used it where they would put it on the chart. Charts vary but to me this is a big difference between around Green Dot and slower than say Unique. Looking forward to everyone's opinion.
