Telling myself it wouldn't ever happen to me. I went deer hunting today opening day of rifle season in VA. I took my trusty Remington Model 30 Express in 30-06. The bolt was a little sticky in the morning and I didn't think much about it as I had used grease to lube last time I cleaned it. I figured it was 30 deg the grease was a little stiff no biggie. So I get to my hunting spot and get ready to go head out in to the woods. I pick my spot and settle in for a day of deer waiting. My stomach starts to hurt after about 2 hours and I get up to head back to the car. Met a couple of other guys there from the hunt club and shoot the bull a little. They then take off down the road and I start unloading my rifle I get what I thought is all of the rounds out of it and one wont chamber so I could extract it. some times they catch in the chamber from the last round which this one is. Remember this is a OLD gun pre WWII I believe. I failed to check it out when the bolt was sticking and once again I failed to check the rifle chamber and I closed the bolt on what I thought was an empty chamber and BOOM. I had the rifle on the back trunk floor of my matrix pointing down it shot a hole in the floor board and into my muffler scared the daylights out of me and almost had be soil myself. The other guys came back to see what was going on as we were parked at the range. I told them and calmed down a little and drove home. I am done hunting for a few days. I think I am going to retire that gun and look at getting a new deer rifle. I feel like such a dumbass.
