What are your powder choices for a 20" barrel with a 1:12 twist shooting 150 grain SMK's and Barnes 150 gr, Tipped TSX'S?

I'm getting about 200 FPS below published data with IMR 4064 and Varget. BLC(2) has been recommended as a faster powder, better for shorter barrels, what are your choices for 20 inchers?
