SReagle, Glass-bedding the barreled action is a process whereby a product such as "Acra-Glass" (from Brownell's) is mixed up and placed in a roughed out stock at the points where metal meets wood. It then hardens after a brief time and becomes a permanent part of the stock. The idea is to keep the barreled action from 1. moving in the stock under recoil, 2. preventing moisture in the wood (humidity, etc.) from warping the stock thereby putting unwanted pressure on the metal, and 3. dampening barrel vibrations contributing to better accuracy. That's pretty much the basic description of "bedding". Free "floating" the barrel is a process whereby only the first inch or so of the barrel is bedded, right close to the receiver, (either with Acra-Glass or simply stock wood "contact") and the "rest" of the barrel is "floated" off any contact with the wood stock thereby called "free floating". There are pros and cons with either bedding the "entire" barrel or "free-floating" it, that affect ultimate accuracy of the rifle depending on various factors involved such as type of cartridge, overall weight, barrel size, rifling, bolt movement, etc., etc. This is a "brief" description of what you are asking!.............................Dick :idea:
