A glass bedding kit from Brownell's only costs about $11. Now if you already have a dremel tool and a few hours worth of time the ability to follow directions and a few days for the bedding to cure you have very little to loose by glass bedding a rifle. The upside is that it will make your rifle more accurate the only downside is that it might not do anything at all but it will never hurt. Its about the best bang for the buck you can get other than recutting a crown to accurizing a rifle.
