[QUOTE="ntsqd, post: 2349084, member: 93138"] Thermal expansion is important to a hunting rifle that sees large differences in ambient temperature. The EXTREMELY common complaint about traditional wood stocks changing their POI with the weather is directly caused by this. If we're going to add something to the system it makes sense that that something is as temperature stable as possible. Yield strength is important for the bedding material to resist any thermally induced change in the stock. Not strong enough and it warps with the stock. The degree of shrinkage determines just how good the fit of the bedding to the action is. When that fit is poor the bedding or the stock are subjected to large Impulse loads when the action, under recoil, slams into the stock or bedding or both. Classic failure mode right there, results in a cracked stock. I haven't tried flying on any of my rifles, how does that work? Is the FAA going to issue a Cert for this? I think that I'll stick to the RV-7 Express instead. [/QUOTE]
