Nice deer! I had a similar experience (no round chambered) while hunting black bear in Maine. Apparently, the bolt closed without picking up the round. 999 times out of 1,000, I would have opened the bolt to double check out of paranoia, but, of course, that was the one time I didn't. Unfortunately, the bear heard the "click", since he was only about 40 yards away, and quickly turned and disappeared into the woods. I thought the round had misfired so I was forced to sit there and watch him walk away. When I opened the bolt a few second later, I was furious to say the least. I then repeatedly attempted to wrap my rifle around a tree, without success. The body of the rifle was obviously built with an eye toward quality and durability, unlike the action.
