How does it fire? First and foremost I would not fool with something that is not broken, if it fires well then leave it alone! If you are having accuracy problems then this could be an issue, the stock could have swelled/warped, the barrel could be warped, the rifle could just have been put togeather that way, hard to tell but you could be opening a can of worms. Some rifles are built with the tip of the stock placing pressure on the barrel, supposedly helps accuracy. You could bed the stock and/or enlarge/true the barrel channel of the stock if you thing it's a problem.
