I am picking up a 223 model 12 LV (cabelas) Monday and am interested to know if the chamber is a 223 or 556. Has anyone been successful getting reamer prints from Savage? I know CZ and some other manufacturers sell 223's but say are safe to shoot 556 rounds out of them. Of course they label them 223 for marketing reasons and chamber as 556 for safety reasons. If the 12 LV has a true 223 chamber I would like to know it. I suppose the literature with the gun might say. I appreciate if anyone has insight into this.
