I glass bedded my Savage bolt action 22-250 by using a Dremel and making deep cuts where the action lies. I also used course sandpaper on a dowel to make the barrel clearance to free-float the barrel.
If you are methodical and careful about what you are doing, it can look great and function even greater!
I am pulling 1/2" groups at 200 yards (off the bench) with 50g TNT bullets (muzzle velocity) 3,920 FPS.
That's a lot better than before I worked on the gun!
