Thank you once again Sir.

I omitted part of the story. It's not my M-S, although I'd love to change those circumstances. A friend was asking about the markings on a rifle held by his friend. Neither of us were familiar with the "NORM" designation so I posed it here. His friend shoots 8x56MS out of it and has no doubt about either the bore or chamber. All three of us were just wondering at the meaning of the caliber marking.

Cheers!
