When I guided hunters,I never let them put a round in the chamber until it was time to shoot. I bet I heard a thousand times,how they were safe, and I could depend on them....... ya right. I watched many a hunter trip and fall over a tree or rock, and take a tumble. They were barely safe with an empty rifle,let alone with a round in the chamber. My boys and I also hunt with empty chambers. It has never cost us a deer or elk. When calling, a round in the chamber is the last step,and the first step when done calling is removing it.
