What is the truth about the bore diameter on an SKS? I have heard two different things back and forth constantly. I was told years ago that the SKS had a different bore size than a .308 or 30 caliber. I know the 762x39 typically shoots bullets around .310 to .312 (I think). I was told first that the barrels were a larger bore accordingly...Now I have also heard from a few people that this isnt true....that in fact the SKS bore IS the same diameter as most other 30 caliber rifles, and one person told us that the lighter weight/larger diameter bullets are used to increase chamber pressure so that the SKS action and bolt will function reliably as a semi-automatic. Does anyone here know absolutely what is the truth? Sorry for being so long winded about it, but I dont know how to explain what I am asking in simpler words. I am not a gunsmith or anything. Please help. I am sick of all the unoficial opinions and guesses as to what is true and I dont think I could think of ANY way to actually measure it. Thank You Thank You!
