I tape the front, sides, and bottom of the lug.
Just curious what your rationale is for taping the front, sides, and bottom.
In short, "stress free bedding."
I don't believe there is any benefit for the lug to contact the bedding material in those areas when the action is torqued down. If there was any flex in the forearm of the stock, to me it seems there is more potential for a shift in POI when the lug has full contact vs. just contact at the rear. It also makes it easier to pull the barreled action out of the stock.
