Powder type (ball, extrude or flake?) for the .300 whisper.

I used H110 with 240 grain SMK, but when I started reducing charge weight to get to 1050 fps SD and ES increased significantly. I started using N110 and things went better. I think I will also try some AA 1680 because others who have experimented with it have liked it. I am only really interested in subsonic performance, but I did load some 147 grain LC bullets just to plink with.
