No one seems to ask just how often the average
shooter actually breaks a wooden stock. Or what would happen to the rest of the rifle if it were subjected to loads severe enough to snap the stock. Or even if synthetic stocks are actually harder to break than a wooden stock.
Would you be surprised to learn that the common injection molded stocks used by most of the big gun companies are not significently harder to break than a walnut stock, and much easier to break than a laminated wood stock?
It is interesting that in the United States rifle stock design has received more attention than shotgun stock design. Many more custom rifle stocks are built every year for US shooters than custom shotgun stocks, even though shotgun stocks are far more critical to hitting the target.
By far the most popular style today is the modern classic stock which tends toward a straight comb with little or no drop at heel, a pistol grip with a medium curve, and a rounded or pear shaped forearm. The buttplate is usually metal, black plastic, or solid rubber. Stock finish is usually satin (if sprayed on) or traditional oiled walnut.
European style stocks seem to favor gentle convex curves rather than straight lines from comb to heel and between the pistol grip and toe of the buttstock. Cheek-pieces, if present, are frequently of the "pancake" type. Modern Euro-style stocks usually incorporate a Weatherby-derived pistol grip. Buttplates are usually hard rubber, black plastic, or occasionally buffalo horn, and recoil pads are used for hard kicking calibers. The finish may be glossy or satin.
Rifles with California style stocks are seldom supplied with iron sights, so the stock is designed expressly for the higher line of sight of an optical sight. These stocks usually come with a durable high gloss finish that shows off the grain of the select walnut to beautiful advantage.
The best wood for solid wood stocks is generally considered to be walnut. A satisfactory stock must have certain properties, and walnut fills the bill better than other woods. For example, stock wood should be reasonably hard but not brittle, stiff and dense without being excessively heavy, take checkering well, and have attractive figure and grain. The thin shell European walnuts are particularly durable and attractive.
Other, cheaper, solid wood stocks are made from various hardwoods, primarily beech, a light colored wood with little grain or character. So it is usually stained to resemble walnut. Such a stock is satisfactory in use, but nicks and scratches reveal the white wood under the walnut finish. These cannot be touched-up, as could a genuine walnut stock, and soon the "walnut finished hardwood" stock starts to look really tacky.
Laminated wood stocks are actually the strongest and most stable of all stocks. Functionally, they are superior to both solid walnut and the synthetics. If laminated from decent woods and well finished they can be quite attractive. They are cheaper than solid walnut stocks because they are made from smaller slices of wood, most of which cost less than good walnut. The grain in the various layers of wood is designed to run in different directions and cancels out any tendency of the stock to warp. When properly glued under pressure and sealed, laminated stocks are immensely strong and warp resistant, and virtually impervious to the elements. Laminated stocks are generally regarded as the stiffest and most accurate type of stock.
Rifle stock design is a controversial subject, and the source of much disagreement among gun buffs. There are several schools of thought as to material, decoration, finish, and most of all the shape of rifle stocks. Most of the controversy is around the stocks of bolt action rifles.
All of the above styles can be attractive if properly executed, and all can be functional. And, of course, beauty is in the eye of the beholder.
