Well, I got to shoot the HS-6 loads today along with WSF & AA# 5 loads. All Max by the book.
7.0 Grs HS-6...7.0 Grs. AA# 5...5.7 Grs. WSF with WLP primers and Ranier 115 Gr. RN @ 1.135 O.A.L.
I shot them in a 16" barrel CX4 Storm, a 5" barrel Bennelli, & a 3" barrel EMP.
CX4 Storm - 16"

The WSF gives practically the same velocities as the others with less powder and less recoil. The AA# 5 does give better velocity in the carbine, but not all that much.
The WSF and the AA# 5 were very clean and very accurate. The HS-6 was not as clean nor as accurate, although it was not to bad.
WSF is my new favorite 9MM powder. It would easily shoot through one ragged hole at 15 yds out of the CX4 Storm with the scope on 1.5X. So would the AA# 5 as far as that goes, but WSF has less recoil and is more pleasent to shoot.
WSF is very clean burning and leaves the cases pretty clean, very clean in the EMP where pressure was greatest. (tightest chamber)
None of the loads showed signs of high pressure. I shot them at 86 degrees. I left them in the sun for a while to get them to ambient temperature before testing.
Oh yea, Please Reduce 10% to Start.
