I have tried to search all over Google and have yet to find any specific post on bedding a base in addition to lapping the rings. I have a 20 MOA Nightforce 1 piece base for a Remington 700. I do not currently have it, but am assuming the worst that the base tightening will not be flush(one side at a time to check for gap). 1) Will bedding the base cancel out the 20 MOA correction that the base has built into it? If only bedding the side that is off. 2)If you bed the base of the rail will lapping the rings in addition be wise? The way I look at it is that bedding the base, if even needed, will not bend the rail slightly and lapping will allow maximum contact with the scope. I could be wrong the way I am looking at it. They are both minor jobs and inexpensive, but have always had the philosophy to do it right the first time.
