I will offer a dissenting opinion on the fragility of so-called plastic stocks. For many years I carried a Centurion M'17 .300 WM in a Bell & Carlson injection moulded plastic stock. It was the best! Except the trigger guard was too small and I couldn't get my gloved finger in to take a shot at a very nice buck.
A plastic stock, as a generic term, cleans up with a toothbrush. If it gets dropped, meh so what? No one sits in their flannel checked shirt rubbing a loving hand across long chain molecule polymers the way they do over highly figured select hardwood. If it takes a tumble, the rifle gets brush off and back to the job. You haven't devalued it a nickle. And, unlike wood grain, it isn't likely to fracture along a hidden fault.
If the air temp is deep double digits cold, your hands, feet, skin and eyeballs are going to suffer. Yes, you rely on the rifle to do its job, but I suggest put your brain energy into figuring out warm layers and wind protection, not the stock.
