Changing the gas block setting will not affect the initial pressure of the fired round. Adjusting the amount of gas will dictate how vigorous the actions cycles. Adding a suppressor can affect the dwell time and back pressure on your 6.5 Grendel. I adjust my gas block so it locks back by the bolt catch on an empty mag. My spent brass land at 3-4 O Clock but I don’t use a suppressor.
Just curious if you lapped the face of your forged upper receiver or did you use a billet upper. It is suspected that if the barrel and bolt are not in alignment additional wear can be imparted on the bolt and barrel extension.
