6.5 saum 6.5 gap

Does anyone have any load work ups and or a good start point?? Using 140gr Berger’s 26” proof carbon barrel on a SA Stiller Tac30.

Anyone try using H4831SC for the 6.5 saum w/ carbon barrel?? I’m getting 3000 fps w/ R26 out of 26” barrel. I’d like to push out to 3100 plus if I can
