Like Questor said, the GOOD syn. are better than wood, with emphasis on good. What I mean is (probably Questor as well), is that the cheap, injection moulded plastic types can be soft & must be bedded with a good, hard compound before they are useful. I like the HS type stocks with a alum. bedding block & then skim bedding those. From a pure use standpoint & not looks, this type of stock has to be better than wood. Just as good is a Lam. stock that is bedded & if practical, pillars installed. This will make it as stable & possibly tougher than most syn. stocks.
Handwerk, you say you don't like Lam., but some coat the stock with tru oil or tung oil & you can make the lighter wood darker & the stock can be more attractive, more like wood. I have some pure wood stocks too, & with most I have not had trouble, but in a couple of cases I have. Do you want those rare occassions to occur at the wrong time, may never happen to you or it may.
If you want wood, you can have you cake & eat it to a degree. Have a Smith that is good at it pillar bed/glass bed your wood stock & free float it,
but in the barrel channel line it with glass also. Some will dig out the channel & install a steel rod or pieces of glass or carbon arrow shafts. Bed over those & put tape on your barrel to give it just a little clearence for the float. If a Gunsmith knows what he is doing, you will have to look at the gun close in order to see it is bedded. Coat the outside with a good gunstock oil & you now have a beautiful wood stock that is impervious to
the elements.
