Joe I answered on the basis of the 2nd sentence which seemed to me to imply that any shell which did not exactly match the chamber in length was not the shell it was chambered for. This is simply not the case. Of much more importance than exact length match is to fire "The Load" the gun was designed & chambered for. This may very well not be an exact match in shell vs chamber length. One could very well put up too heavy a load in the shorter shell & a proper load in a too long shell. The point is there is much more to be considered than just length of the case. Many of the older guns are chambered for 2 3/4" shells, particularly in 12ga. This emphatically does not mean they should be fired with just any 2 3/4" load that can be bought, yet one might well say that it was "Chambered" for that length shell. The reason, I for instance, might decide to load 2 3/4 cases for firing from one of my damascus 2 5/8" chambered Lefevers would likely be my loader was set up to handle that length & I prefered not to be re-adjusting all the time. It is nice to have the knowledge that as long as I put the proper load inside the extra 1/8" of case is of no importance. & no it won't wee any higher up the wall or knock a squirell out of any taller a tree, just a matter of convenience.
