I appreciate the information. The gun I was thinking about glass bedding is a Weatherby Mark V Ultralight weight in a .270 Win caliber. It has a aluminum bedding plate which should eliminate the need to glass bed. I was hoping that by having a bedding job done, it would tighten the target groups up a little. The other rifle I might glass bed is a Remington Model 700 BDL in a 7mm Rem Mag, but it shoots very tight groups (even with me behind the gun) with reloads of Nosler 150gr E-tips that I nearly finished fine tuning. So I hate to mess with it.
