RE: Remington 7400
I still keep my 7400, I have had it for over 18 years. It has dropped more deer than you could throw in a dumptruck. It has worked flawlessly. I rarely use it anymore, but try to take it out at least once a season. Too many other toys to take out. There are a few tricks to them. I have had to take out some material in the forarm because the forearm screw was putting pressure on the barrel. Also, go easy on the oil in the action.
Right now, I don't have a scope on it, and use it if I am on drives or hog hunting.
