I have not looked close at your rifle but many times there is a small screw near the trigger or a way in which you can lighten the trigger pull to a respectable level. A hard trigger will really make it frustrating when shooting your rifle sighting it in. It creates more of a tendency to pull your shot.

Look in your manual that came with the rifle and see if there is not an adjustment screw. If not, give traditions a call. Sometimes all it takes is to pull the trigger assembly and clean and oil it real good.
