Depends on the laminate, but the idea is that the wood is impregnated so it cannot take on moisture. They are more durable in terms of withstanding a shock and not fracturing for the same reason. I do not have any on my hunting rifles because they tend to be very heavy. I for one do not find that the feel of laminate is the same as wood. I like a wood stock for the cosmetics and feel, but laminate does not carry the same traits despite the look. I much prefer a synthetic stock for the purposes of a hunting rifle that will see a variety of weather. With the wide variety of high quality synthetics available today, most can find something that is aesthetically pleasing. I just need more $$$$ so I can swap out more to the good stuff (HS, McMillan, etc).Although I love wood, I tend to agree that a synthetic stock is more trouble free. Does anyone know if the laminate stocks are a legitimate compromise? That is my belief, but I don't know for sure. Have a laminate on my varmint rifle, 204 Ruger, and like it fine. I've never used it in harsh weather though.
My preference is laminate. Synthetics are cold to the touch in cold weather, and there is no such thing as reasonably priced figured walnut. A few years ago, I did some work with a speargun manufacturer, who was contemplating marketing a laminated speargun. He secured some laminate samples and boiled them for four hours to test durability! No swelling, cracking, or delamination. That's durable! The only drawback is that laminated stocks are generally heavier than wood, or synthetic stocks. Alas, life is full of compromises.synthetic all the way, if I had to go wood I would get a laminated stock. They are tougher than plain wood stocks, and feel just as good.
BOESHIELD was developed by Boeing for use in the aerospace industry as a protective coating against moisture/rust. When used as directed, it is very effective. I treated a SAKO .375 H & H and used it on a black bear hunt in Alaska a few years back. After a week of hunting from a skiff with daily salt spray baths, the SAKO was rust free. Three other hunters using Rugers and a Blaser with less effective protective coatings developed a fine red patina of rust on their guns by the end of the hunt. I have also used BOESHIELD on dive knives in the Caribbean for up to ten days without retreating. The knives remained free of rust despite the humid climate and repeated dunking in the Caribbean Sea.Nothing nicer than an attractive, well executed wood stock. Having said that when going on an extended hunt such as the backpack style hunt you mention I'll choose synthetic every time. To qualify that it has to be a good composite and NOT one of the cheap Tupperware injected mold type stocks that come on cheap factory rifles. To further protect the rifle I'd go beyond the stock and make sure the metal is protected. If possible a good Cerakote finish is about the best there is right now that can be done at a reasonable price. If looking for a type finish you apply yourself to the metal that is simple, doesn't cost too much, and gives great protection for a hunt try "BOESHIELD" available from Brownells. Comes in a bottle, just apply with cloth, let it dry, and wipe. Really great. It works as I've used it on shotguns in fowl duck hunting weather and rifles under snowy, wet conditions and it does protect your metal from any rust forming.
