I invited a friend down one time to deer hunt, and he had a 7400. It was about as reliable as a politician. It might as well have been a single shot, because all it ever did was automatically jam. Neither he nor I could ever get and keep things clean enough for it to function reliably.

My suggestion if you want an autoloader would be to get a model that has seen military service at some point in time. Accuracy won't equal a bolt gun, but it will be good enough and reliability shouldn't be an issue.
