Someone's just asked me how come I'm so sure about the Indian rifle CHS spec. I have to say that I'm NOT sure. It's just that I question why every other bolt asction 7.62mm Enfield is between these two specs, why wouldn't the Indian rifle be the same.
The same answer applies regarding the question as to why they all seem to close over the 1.635 no-go gauge. Once again, I'm just using my old Armourers 'bleedin obvious' assumption that these have oversize CHS with worn bodies and were disposed of as a result.
If anyone wants an unknown 7.62mm CHS gauge calibrated, then just ask and I'll do it. But the lcalibrated length/answer will be to the UKMoD standard
