Everything checked over tight at the end of the day, nothing loose, nothing obvious. Nightforce was mounted pretty close to the bell and there is no signs of slipping. Unless the nightforce failed from 30 rounds of 308, which would be mind blowing. Suppressor has no signs of any kind of rubbing let alone any cap or baffle strike. Maybe its just a cursed setup and hates me despite throwing literal thousands at it.
I don't know that its fouling causing the issue, That's just the first thing my mind went to since it was all the same bullet and getting worse as more rounds were fired regardless of hot or cold barrel.
As for shooting setup, no lead sled or similar here, just some old caldwell bags to rest on and a good heavy stable bench and seat. One for front one for back and my shoulder providing the recoil absorption.
