Re: Standard contour barrel in varmit contour stock?
If you were going to bed that action/lug to the new stock...might look OK. You would want to wrap the barrel with many layers of masking tape before bedding (to keep it centered in the stock). Don't see any problem with it. Might want to sand the channel, stain and seal if it has any wear spots first.
My 700 Varmint barrel (.820) sits in a HUGE channel in my AICS 2.0, but it does not look bad at all.
