If you plug in the Litz BC for the 129gr SST, it is higher at .495 G1, .247 G7, but that won't change your numbers noticeably at close ranges.
Hornady lists a max load of 26.2gr of 8208XBR under any of their 129gr cup and core bullets in 6.5 Grendel.
I would look at CFE and LVR if you want more speed, because you could likely get a 129gr to 2300fps from a 14.5" with either of those.
Expansion on the SST stops at 1800fps.
What's your optic height?
With your current speed, you will have expansion just out a little past 200yds.
If you use LVR or CFE and get up to 2300fps, you will have expansion out to 315yds and a flatter trajectory.
