I prefer wood stocks as well...My deer rifle is a 1980 model Ruger M-77...Every few years I remove the action from the stock and give the trigger group a good cleaning and put a couple of coats of boiled linseed oil on the stock and I'm good to go...I have been caught in the pouring rain with this gun and have never had my groups move because of stock warpage....I did free float the barrel a few years ago (maybe 20) but I never had any problems with groups moving even before I did this...

Now my brother...All his bolts have synthetic stocks, but he's hard on a gun...Sometimes I think he drives fence posts with his the way they look, so it just depends...If you are the type that cleans your gun and oils it up after every use, go with wood and blued steel....If you are the type guy that seldom changes the oil and filter in your pickup....Go with the synthetic and stainless...
