I have them all - but when it comes down to hunting in the most inclement of weather - it's the laminate one that comes with me. Laminate is not quite wood. Let's call it what it really is - PLYWOOD - but it is closer to having a soul than some kind of synthetic. My CZ 550 LUX is the one that really brings me comfort though ....
As a carpenter and cabinetmaker, if I could nitpik for a second...
Plywood and laminate are actually not the same thing, though the difference is the kind of thing that probably only woodworkers would care about.
Plywood and laminate differ in two ways.
First, the layers in plywood - the plies that give it its name - are almost universally thin - usually 1/8" or less. It would be very hard to find any plywood with thicker plies than that.
Laminate, on the other hand, is often made of layers that are thicker. When you get a "butcher block style" counter, for example, it is typically made up of staves around 1"-2" wide that have been laminated together, yet most people would just call that a "wood counter" . Similarly, let's say you by a nice harvest table made of solid oak. That table is 32" wide, yet there are no oak planks out there which are 32" wide! If you look carefully at that table, you'll notice it is made up of narrower oak planks - probably around 4"-5" wide each - laminated together. Yet that table would still be sold as "solid wood" . In any case, while the layers in plywood are almost always thin, the layers in laminate can be and usually are wider.
Second - and this is the more important one - the layers in plywood are always stacked perpendicular to eachother, while the layers in laminate are always aligned in parallel.
So when stacking the layers of plywood, on the first layer i'll orient the grain running left to right. On the second layer i'll orient it up-and-down. Then the third layer will be back to left-to-right, and so on. These cross grain layers give plywood its seasonal stability, since wood typically moves seasonally across the grain, but in plywood each layer will keep the neighbouring layers from moving. (This is also why plywood layers have to be kept thin - thicker layers would be strong enough to break the glue bond and move anyway).
Laminates are always layered with the grain direction aligned. That does still make the product more stable than a similar sized chunk of solid wood - but not as stable as plywood.
In the case of laminate rifle stocks, all the stocks i've seen have used thin layers of lamination - almost or as thin as typical plywood layers. This would increase stablity even farther, but it would also start to make it look a lot more like plywood. But, the fact that you can look down on a laminate stock and not see end grain every other layer is how you know you are looking at laminate wood, not plywood.
Ok, nitpik over.
