The charge is 10.0 Herco based on 9.0 as a max for a standard 230 jacket an 11.0 being a max load for a 260 gr jacket from the Speer #12 Ruger data . That works out the Centennial Ruger BlackHawk likes 9.5 gr of Unique with these . 7# of Herco followed me home a couple of years ago really cheap .

Looking good! 10.0gr should be perfect. I’ve always used .5gr more of herco than unique. So if your revolver likes 9.5 of unique, 10.0 of herco would be spot on.
