Random question, is the barrel fully secured into the action? No chance of anything moving mechanically? Suppressor is fully locked in, no wiggle at all? Is the barrel fluted, fully stress relieved and everything true in line? Bolt nose fitting the chamber end of the barrel, nothing weird there? Screws all clear of the bolt inside the receiver? Recoil lug not moving in the stock and receiver recess?
Something will be causing this, but finding it can be a mission.
