It appears the chamber dimensions are also quite standard. I would hope the chamber dimensions are not likewise militarily sloppy.

Daryl, no the chamber seems quite tight... certainly nothing like the Martini-Enfield which used to produce profoundly 'pot-bellied' and banana-shaped fired cases

When running the fired cases from the Ruger No 1 through a FLS die, the shoulder is barely set back at all vs several mm of setback when resizing fired cases from a SMLE or ME.
