First off, tell us what size groups your particular gun is shooting. You may or may not be expecting too much from an off-the-rack factory rifle. If various brands of factory ammo are available for it, have you tried them to see if the gun perfers one over the other?
I imagine your rifle has pressure points in the forearm under the barrel. This is done intentionally to put a little upward pressure on the barrel. Some guns shoot acceptably with it, some do better with a free-floated barrel, where the pressure point is removed. I have rifles that shoot well with the barrel pressure, and also ones that shoot best free-floated. Glass bedding generally refers to making certain that the action and an inch or so of the barrel ahead of the recoil lug are in solid contact with the stock and there is no warping or torquing of the action, and the recoil lug maintains soild, even contact with the stock on it's backside (toward the action). Some folks do their bedding a little different, but this method has given me good results.
Perhaps the best thing you can do is to become a handloader if you wish to try to wring as much accuracy and repeatability out of your gun as possible. It's both a very rewarding and sometimes a frustrating hobby. It's no secret that guns are individuals unto themselves, and totally identical rifles may not shoot the same ammo the same.
I guess that is my take on your situation. I'm sure others on here will give you their opinion of what path you should take also. Good luck....
