Marc,

I find 1 oz of 7 1/2 shot in 12 gauge or 7/8 oz of 7 1/2 shot in 20 gauge at around 1200 fps works well for grouse for me. I find 7 1/2 shot works a little better than 8s.

That said, hunted late Decemeber with a guy and his big running dogs. For late season he liked 1 1/2 oz of 6s in his first barrel and 1 3/4 oz of 5s (both turkey loads - max drams)in the second barrel for late season grouse. I thought it was excessive, but he got 3 grouse that day and I didn't get any. FWIW.
