Those look a little big for a 7.62 cartridge...more like 9mm or .45
If those are kills....damn.
Honestly, now that you say that I do think they are bigger than 7.62 but I'm going off memory and that doesnt mean squat, mabey there from the gas tube, or are the marks way to small for that do you think? I guess I'll just have to wait and see....darn work gets in the way of everything
Too small for the gas tube...I don't have any stocks similar to that to gauge the size...it would make sense if it was the caliber on hand, they just look a little big. If this killah was such a bad ass that he could find his still hot shell casing, after a kill and burn a mark into his stock...he is likely the deadliest man to ever carry an SKS. To predict where they land would make him a geometry mastermind as well. I would be interested to know where the casings land when you fire this...if they land in a tight circle rather than all over the place like most SKS's do..you might have the Rolex of SKS's
