A while back I bought a Carcano 91/38 that was a real beater. Spray painted stock, rusted metal, broken sprints, etc. After fixing it up everything looks and acts the way it should while the rifle is empty. When a round is loaded in though the action becomes very stiff and the bolt is hard to rotate. Could it possibly be the ammo? I read somewhere that the round should go up to the casing if you put it in the end of the barrel. It does not do that on the Carcano. It does with my Mosin Nagant. Other then the stiffness it seems to chamber the round just fine. I was using PPU 6.5x52 Carcano. The barrel has 6.5 stamped on it and traditionally the 91/38's where chambered in this. I have not shot the rifle yet. If not the ammo what else could it be? Any thoughts and advice would be greatly appreciated. Thanks in advance!
