Gunman;
Note the original question here does not state this to be an English gun. My last answer here was bsed on the assumtion it has wear compensating (tapered) bolts. These will in most guns allow the lever to rotate to the left of center for the purpose of wear compensation. In the case of a tapered underbolt if the bbl moves forward off face the bolt will advance by the same distance the bbls have moved, which will allow the lever to rotate left.
On a gun properly on face the bbls should seat against the standing breech leaving a few thousdanths gap between the flats & action flat. Slight hinge wear will allow the bbls to close against the flats which will in the case of compensating bolts cause the lever to rotate slightly further left.
"IF" though the gun is properly on face the bbls should not be brought further to the rear causing the gap between the flats to be increased for the purpose of compensating for bolt wear.
As I said in my last post we have two distinct wear points & these shold be treated individually, though the one can have a slight influence on the other in some cases.
