I didn’t shoot it very much, but I did find some notes in my reloading data:

just under .9” (pretty good for me with a semi auto) 123 ELDM 2456fps with 27.8 XBR
 
Twist rate?
Gas block journal?
Rifle gas port location?

Sounds like 6.5 Grendel data not 224 Valkyrie.
 
Sorry I have a Grendel for sale also and got confused!

.750 gas block
1/7.5 twist
Believe it is rifle length gas, will confirm

looks like federal 90 GMM factory was just under or over 1”, best group 0.65” for 5 shots
Hornady 88 ELD factory ammo 2670 FPS, same accuracy just under or over 1” with me shooting
