    Judging by the serial no. you have and old one and it is almost certainly something less than 2 3/4". However, this situation can be easily remedied by any gunsmith with a 16 ga. long forcing cone reamer or 2 3/4" chambering reamer.

    That may well be, Mr. Honda; but if you measure a loaded 2 3/4" shell you will find that it is only about 2 1/4" long. So, naturally it will fit flush in any chamber longer than 2 1/4" and that proves nothing. The problem arises when you fire that shell. If the chamber is shorter than 2 3/4" the mouth (crimp) of the shell fails to open fully and a large number of shot bounce off the walls of the bore instead of proceeding straight out, which causes them to be of irregular shape and inaccurate. Therefore, to be sure, you must measure the chamber with (preferably) a chamber depth gauge; which is nothing more than a smooth steel rod of the appropriate diameter with various depth marks on it. It is inserted into the open breech and the mark that fits flush with the mouth of the chamber indicates the depth. Your gunsmith should have such a device, or you can purchase one from Brownells.
