Thanks for the info.
If a good powder comes out, I tend to buy it early on before the demand goes up (along with the price!)
I started using VV powders in 1990. Now the price is steep. When the Accurate powders first came out, imported from Israel at that time, I tried them because they were priced really well (read: cheap). Now they are usually priced more than Winchester, Hodgdon and Alliant.
I'd like to get more of the Ramshot line but those powders are perpetually out of stock. I've known that Silhouette is the same as the discontinued Winchester powder, WAP, for quite some time but never see it available. I still have some 4# bottles of VV3n37 but when that's gone I'd really like the WAP for my 9x19 luger, and 9x23 Winchester.
