Hello Bowhunter,
I assume you are talking about a Thompson Center Encore with a 308 barrel. If so, I will be here to tell you that the sting with wooden grips is more severe than with the rubber grips. I have two 308 barrels and I have tried the wooden grips. I switched to the rubber girps. Several of my shooting buddies bought the hand made and fitted grips from Bullberry. They have switched to the rubber grips for recoil reasons.
