Go with the 107gr SMK on top of 8208XBR or AR-Comp.
Litz BC on that bullet is much higher than we normally see attributed to it, like .461 G1, .230 G7, and you can easily get it over 2700fps from a 20-24" Grendel in most cases.
Book loads are in the 2730fps range with older powders from a 24". 2680fps from a 20" with AA2520.
I have an accuracy node at 2625fps with 8208XBR from my Lilja 318 and not even near the max charge weight.
