Nothing can replace a beautiful hunk of European walnut to me.
I love the look of the Weatherby Euromark and such, although those types are too precious to bang up in the field.
My Remington 700 Classic has very beautiful wood, without being so luxurious that I won't hunt with it. In fact, it is my primary deer rifle. Only synthetic bolt gun I have thus far is a Savage 10 FCP-K Sniper.
