Speer 14 lists 6.3 - 6.9 grains AA#7 with their 100 grain jhp for 1094 fps (max load) from a 5.5" Ruger Single Six.
For me with an SP101 or a Single Six only, the max load is my starting load in 32 H&R, unless I'm looking for a light target load.
If you have a smaller S&W or a H&R revolver I would stick to the book data.
