Re: What are the basics for setting up a stock?
It depends on your expectations. The stock is just one component in the shooting system.
If everything else about the rifle is factory, then (1) drop it in and torque it down evenly, (2) check for clearance/fit and barrel floated, and (3) shoot. If the performance meets your expectations, then you're basically done.
The next step up would be to bed the action and first inch or two of the barrel to fill the voids between the action and bedding block.
Otherwise, you're really getting into action blueprinting, precision machined/pinned recoil lug, etc.
The main distinction relative to stocks without the aluminum block is to ensure that pillars or support goes all the way through such that the stock can't compress or allow the torque to change in the action screws over time and with varying environmental conditions.
Marine-Tex is my preference for bedding. But, many have success with other materials.
