It's the wood is right, and it's the wood because over that long a time it shrinks and often splits whether you shoot the gun or not. Once it splits it's more likely to fail, especially with heavy loads. A lot of vertical cracks in stock heads can not be closed and glued without relieving some wood around the receiver. I've seen that a number of times. You close and glue a crack up and the stock will not go back on the gun.
