My marlin .22 mag I believe is the 882, something like that. I have owned it since I was a kid, it never grouped very well. The trigger is stiff and the barrel rubs all the way down. I can dremel the channel to open it up but its hollow inside the stock under the action so in order to bed it, I would have to fill it up. What have people done to help with this? I have looked but with no results, I cant find anywhere that sells stocks for them or even a new barrel. Also, I may have to upgrade to a rifle basix trigger one day. Any thoughts
