[QUOTE="J E Custom, post: 612429, member: 2736"] All different materials have a different coefficient of expansion. but in a properly bedded action the bedding thickness is minimal and has little or no effect on expansion or contraction. Most bedding materials are low shrink materials in order to maintain contact with the action at all times The main reason for pillars in the bedding system is to keep the action screws from crushing the stock material to the point of yield and lowering the torque on the action screws. All stock materials can become compressed over time with the exception of the machined aluminum stocks. Pillars will expand and contract based on the material used but with recomended torque loads they will not compress and remain in that condition. If good pillars and metal to metal to metal contact is achieved re-torquing is rare unless you remove the action from the stock. J E CUSTOM [/QUOTE]
