For the match rifle, Arne Brennan had really good results with N530 back when there were discussions about all of this on the target side.
He was using longer barrels in the 26-28 range, pushing 130gr JLKs with N530 and another powder.
You can also shoot the 107gr SMK really fast with 8208XBR and get exceptional accuracy and tight SDs.
8208XBR and AR Comp will give you excellent SDs, and you can use those in the bolt gun behind 123gr with less worry about spiking pressure, especially if you increase the COL.
RL12 is right in there for ideal burn rate for Grendel with the 95-123gr if you can find it.
Look where it sits between TAC and AA2520, among several others.
