R905 has the same source as Norma MRP and Reloder 22. There are only some differences because each brand uses it's blending recipe to match their published loading data. Btw. RWS lists for a 160 grs KS bullet a max load of 58 grs in a 7x64 at 2790 fps and 55,5 grs for the same bullet in 280 Rem at 2740 fps.
