I have always thought that the SKS was a cool rifle especially the russian ones, but I have always thought of them as being large and overbuilt to be chambered in an intermediate assault rifle cartridge like the X39. It seems to me that a full size rifle needs to be chambered to a RIFLE cartridge. And I thought it would be very cool to have an SKS in 7.62X54. Why didn't the russians ever try this? Would it even be possible?
