With the gas port at .093", could it be possible that gas could get to the front side of the gas check and dislodge it -- ever so slightly. At a point in the travel of the bullet over the port, the gas check will straddle the hole, but it would not be sealed off. Gas would be acting on the base and travel around the gas check to the inside edge/groove. Maybe the reason why some are having such accuracy problems with lead bullets.
Your measurement has to be it. My divots in the sabot skirts measure the same.
