Re: 20g Field Grade
Fielding: no vintage double should presumed to be safe, with any load, until it has been evaluated by a doublegun specialist. Please look over https://lcsca.clubexpress.com/content.aspx?page_id=274&club_id=43784
You should not use 2 3/4" shells in a 2 1/2" chambered 20g and I would advise against lengthening the chamber. If the chambers have been lengthened, it is critical that the end of chamber and forcing cone wall thicknesses be measured.
