Hi there,
I was always cureous if any of you have ever bothered to measure the actual bore diameter, say at a muzzle. Having a nominal diameter of 7.62 mm, how unusual is it to see 7.63-7.65 mm on so-called "un-issued, unfired" SKS's?
So far I was lucky to find only one that has exactly 7.62 mm as measured by a pin gage. All others I checked/have are all over the place, mostly in a 7.64-7.65 mm range.
Basically, my question comes to this: can "un-issued, unfired" SKS have a bore diameter larger than 7.62 mm?
