When we talk to rifle manufacturers and talk about stock prices it seems that standard wooden stocks are the cheapest option. No moulds or huge production lay out required, models can change easily. vs even plastic injection moulded stocks that only get cheaper if large quantities are required vs their initial mould costs. The reason why most rifle manufacturers have their base rifles with wooden stocks. Those that manufacture in large numbers have plastic stocks in their base line. Of course wood quality can go up as high as you want.
Cold from the stock depends on the material, internal foam of some composite stocks is one of the best thermal insulators, light weight soaks away less heat. Composite stocks, at least the ones we make have their main mass (highest density) in the action area, or where fittings are. Low density materials or internals where you hold or lean your cheek against.
