I'm rather impressed with mine but it's not the average Carcano if I'm cyphering the markings correctly. The bullseye over crossed rifles marking shown in post #7 suggests it has an accuracy marked barrel. After cleaning who knows how many years of crud out of the bore and using handloads with .268'' bullets it will shoot nice round 1 3/8'' groups at 100yds.
Aragorn, why don't you invest in a box of Hornady 6.5x52 ammo thats factory loaded with .268'' bullets.
