just note that it doesnt mean it hasnt been used or fired a lot it could have started life at 0 or 1 and been shot enough to erode it to a 2. its just hard to tell when dealing with surplus. you would have to have someone with a barrel scope take a look at the throat and rifling near the muzzle for signs of pitting and wear to determine its true status.
gaging only gives you a rough guestimate as to the condition of the barrel. kinda like looking at a carbody and interior then trying to guess the state of the engine and transmission. its a good indicator but not a tell all.
