OK, so you're basically wondering if you need to bed the whole action vs. just the front and the rear. To tell you the truth, I doubt if it matters all that much one way or the other. I elected not to do it. Not only was it easier but I felt there was less chance of stock flexing messing things up when the screws are torqued but I very well may be all wet there. I know some strive for the action completely resting on only the pillars for similar reasons but there are more ways to skin a cat I guess.
A guy posted pics of his McMillan job HERE
and it looks like they did the whole thing...but you never know where they put some tape to make gaps. It also looks like they made life easier by using smaller diameter pillars. But those pics should give you something else to look at. I'm still working on resizing and uploading a bunch more of my own if you'll bear with me. [img]/ubbthreads/images/graemlins/wink.gif[/img]
