FWIW, I load 200gr plated or coated RNFPs over AA#2.
For light loadings I use around 5.3gr - which is in the middle of the 44spl range (5.1gr-5.6gr).
For "almost magnums" I've used up to 6.2gr - about 10% over the upper end of the 44spl load range. But I worked my way up to that level. It works well in my 44 magnums, but YMMV.
I don't down-load W296 or H110. Too many good sources recommend against it. There are plenty of other powders better suited to light loads.
