Yes, it does effect the top lever. The rims somehow expand and exert pressure on the locking bolt so the lever will not budge. Happens every time. Sometimes I can hand squeeze the barrels down enough that the lever will move and the gun open. Other times I've had to bring the gun home and clamp it delicately in a rubber jawed vise to release the bolt so the lever will move. I'd be pretty sure his problem with this gun was just that. The cure for me has been to never shoot AA hulls in my DH12. I can shoot anything else, and especially old paper ammo, all week long with no issues. AA rims are not round so are prone to stick in the round rim recess. Put a hull standing upright on the bench and hold a caliper against the rim as if to measure the diameter and rotate the shell and you'll see how out of round they are.
