Skim bedding and pillar installation on a Remington 700
The rifle we are working on is a Remington 700 308 in a McMillan A5 stock and Surgeon bottom metal we built here. The stock was inletted for the bottom metal by McMillan prior to installation. Since the pillars supplied with the Surgeon bottom metal were snug in the stock inlets, we initially installed them with some success and the rifle shot between 1/2 and 3/4 minutes.
In an effort to improve performance, we decided to skim and pillar bed the action in place. If you are unfamiliar with pillar bedding, take the time to read this article by Kelly McMillan, it is excellent. It is worth noting that the precut pillars included with the Surgeon bottom metal ensure the correct spacing between the bottom metal and the action so the cartridges feed without issue.
Its worth noting that installation of the pillars is fairly straight forward in this case- the stock has been CNC inletted for the bottom metal and pillars. Installation of pillars in a stock not machined for them is a far more involved task.
