Here's a dumb thing I did on a hunt many years back. My hunting partner brought his new AR platform along and told me how awesome it was, so I didn't even bother to chamber a round in my model 70 bolt gun. I did load the magazine but left the chamber empty even once on stand. Well, shortly after starting the caller, we had a hard charger come in close to us. I kept waiting for him to shoot. NOTHING! I looked over at him and he said, "It's jammed". By that time the coyote spotted us, I quickly worked the bolt and fired. I made a hasty hit as he ran off. There was blood but we never found him dead. So, lesson learned. ALWAYS be loaded up and ready.
