I have read many opinions on whether bedding a scope base actually helps or not. The following photos will show why I think it is not only practical but mandatory for a precision rifle build.
Why bed a scope base?
Quality scope bases are machined to very tight tolerances. The top of most production firearm receivers do not enjoy this level of care and results in mounting a very straight piece of metal (scope base) onto a receiver that has run out.
This run out is very easy to determine and if not corrected can result in vertical stringing of bullet groups.
The way it works is if the front and rear of the base does not lay flat when tightened down, it will bow the scope base to conform to the profile of the receiver. This bow will then keep the scope mounts from lining up with one another and the stress is then transferred to the scope tube once the scope is mounted.
The scope base must lay perfectly flat and in an unstressed position on the receiver.
