It's not just an 85 issue, some of the 75s do it as well. Had to go to a scope with really low pro turret caps on my M75 270Win. It had a VXIII on it and after it jammed on me a couple times in the field, I lost confidence in it. Same deal, brass smacked scope and fell back in port. I replaced the VXIII with an old Vari-X II as it had lower caps, but I still don't trust it.
