I have done it several ways, not taping the lug at all, just the sides, the sides and front (not the lug bearing surface) and the sides, bottom and front. I haven't noticed any discernable difference, so if I can, I do all sides but the rear bearing surface of the lug, as it releases the easiest. That is what I did to the bedding job I posted photos of. This is how that rifle (338 Norma mag) shoots, 5 shots @100 yds

Just my limited experience, more experience people may have more to say. BTW, the sides front and bottom taped off is how McMillan beds their stocks as well. They say it prevents any possible stress from being induced to the lug. Jus sayin.
