I never touch the shoulder and I use a "neck only" die on 300 win mag. I have loaded the same set of cases many, many times, and the bolt is still an easy close. If I had any trouble closing the bolt I would back off the load. IMHO, trying to move the shoulder is asking for a tight spot in the upper portion of the case body. If I had any idea other than to resize the neck to hold the bullet I would full length resize.
