Is it possible (safe!) to shoot 6.5x52 Carcano cartridges from rifle chambered for 6.5x54 Mannlicher Schoenaue

Answer 1

You better check with the manf. of your rifle. 6.5x54 is longer than the6.5x52, and you may force the neck of the bullet case into the breach, instead of fitting neatly. a good rule of thumb is NEVER use ammo other than that made expressly for your weapon. otherwise, you could be in for some serious hurt.
