I've never seen a sterlingworth with pointed checkering. Is this relatively normal and just shows my inexperience or is it a "known rarity"?

Apparently life is black and white to some of you--must be nice. For me, as long as the MEASUREMENTS taken on the barrels as taken by the professional I have do the work reflect safe wall thickness I've lengthened the chambers in mine--and given that my budget mandates field-grade only most have been built like a tank to begin with. None of my guns were original when I got them and even given that some metal was removed, based on the clean bill of health given by multiple respected barrel-guys I still believe my guns are in better shape than when I got them. One mans butcher is another mans craftsman.
