I bought a carcano carbine a few months ago and the guy threw in a box of hornadys. Every one sticks in the chamber. I also tried a few Norma rounds a buddy gave me, and the worked perfect. The only difference is the norma rim is thicker. Has any one else had this problem? Is my extractor maybe to worn to pick up the smaller rim? Mil Surp guns ussally arent this ammo picky.
