Well, using a bolt action, I would spook everything off racking the bolt to load it back up once in the stand. Also, the gun I use, you have to take the saftey off to rack the bolt, which is something that I don't like. My rifle stays loaded from opening morning until the very last day, even in the house. "Unloaded" guns seems to be the guns that kill more people and with mine, my family knows that it is LOADED at all times and there is no room for me making a mistake and not unloading it one day. Which that would be the day an accident would occur. Handle all guns as if they were loaded.
Yea, it was a scary second or two, that's for sure. I was more worried about damaging the gun than it actually misfiring but, you never know.
I had a guy on another forum say that he hooks his to the swivel and felt it was safe. I told him that the swivel could fail and it seems now that you have had experience with that. I told him that anything could happen and it would happen when you least expected it.
This scenerio can also happen with you walking with a gun over your shoulder. I was lucky and the sling disconnected from the stock of the gun. If it was to disconnect from the forearm, you would have less of a chance to catch it. That could be a serious problem to an individual who just might be walking behind you.
