I am reloading Remington STS Hulls with 10.0 grains of Alliant Green Dot behind a Claybuster CB-1075-20 wad & 3/4 oz. of #8 shot.
I load these for my wife's Ladies & Youth Stoeger 20 ga. SXS and it produces little kick .... similar to a 12 ga. Win. AA low recoil round. She has not had any problems with knocking down the targets (when she aims straight) with this load.
Unfortunately it is getting very hard, if not impossible, to find the Alliant Green Dot powder.
