Walnut v/s laminate
Walnut (solid ) is hard, beautiful, and heavy. It can also warp or swell/shrink/dry out and crack, from any number of issues -ie- mounting screws too tight or loose, dropping the firearm, and atmospheric conditions - humidity, drying-out in a arid place, and just plain old expansion and contraction from temperature extremes. any one of these issues can cause your rifle to group somewhere else that day. There is periodic maintenance too. Laminate is basically plywood. It will move, but not to any degree that would affect shot placement, simply because of the grain direction and glue used in creating the stock material. maintenance here too. Synthetic stocks are another animal. They are made from plastics, dam near indestructible, but ugly and proficiently stable, period. Some are extremely light weight, which is a big plus if you are hunting / carrying all day. Every ounce counts when you carry afield. There is no maintenance on synthetic stocks.
