I believe when building a rifle one of the most important criteria is to eliminate any oppurtunity of looseness or vibration. With that said I only tape the bottom of the lug with three layers of masking tape to keep it off the stock. I also put a small radius on all the edges of the lug and when the Devcon has cured I grind a small bevel on all the edges of the recoil lug slot in the bedding so none gets chipped off the edges when putting it back together.
When bedding I remove a lot of stock material allowing for a rather thick layer of Devcon, I also bed as much as the action as possible, from about one inch in front of the barrel nut, all the way back but leaving the tang unbedded. With all this the action seems to snap back into the stock. I have gone back to the range after putting a rifle back in the stock and hit dead center bulls eye on the first shot.
It seems to work good for me, what about you guys?
