OP, how long is your barrel?

Compass Lake Engineering 18” Criterion with JP Enhanced Bolt

Thanks! That's quite a bit better than what I was getting with Varget (105s at 2450 out of a 16: Lilja near max). 

Have you tried using a drop tube to put powder in the case? It makes a significant volume difference for me for putting both Varget and Shooters World Precision in Grendel and ARC cases.
