Roy King Posted May 31, 2016 Report Share Posted May 31, 2016 Hi folks. I have recently been given 5 shotguns. One of which happens to be a BSA 410 I am trying to find out its chamber length. I haven't disassembled it yet as the two screws are very tight , I have put WD40 on them and waiting for it to soak in. When I get it off, any ideas where and what to look for. It has proof marks on the action block but I am assuming the barrel has proof marks on under the forend. Advice and help always welcome. I cant seem to upload photo I have resized it several times but it wont have it . I can email or txt pic to interested parties if required, thanks in advance guys.

Stonepark Posted May 31, 2016 Report Share Posted May 31, 2016 Barrel normally has chamber length on it. Other option is to measure chamber to forcing cone as 410 are all 1/2 inch apart, should be able to determine which it is chambered for. Use a parallel rod slight smaller than chamber and slide until you feel forcing cone. Measure rod length inserted. Put photo up onto photobucket or similar and link to it from post.
