NC Varmint Shooter

I'm having a 6.5 GAP 4S Rifle build, the chamber has .0800 free bore and .2962 neck. It has a 24" Stainless Steel barrel with 1.8 twist. I'm going to use ADG 6.5 SAUM Brass with Sierra 130 gr Tipped GameKing (Gamechanger) bullets and H4831 SC powder with Federal 215 Primers. Does anyone have any recommended starting loads for the H4831 SC powder?
