[QUOTE="bigedp51, post: 1844237, member: 28965"] The best part about reloading is the person pulling the press handle decides how to do it. I prefer bumping the shoulder back far enough to give me some head clearance. And this method also takes the load off the bolt lugs when closing the bolt and prevents galling the lugs. This also reduces the bolt thrust because the case must stretch .001 or .002 before contacting the bolt face. Meaning the case acts like a shock absorber and reduces the dwell time the rear of the case is contacting the bolt face. So all of you who prefer snug fitting cases I hope you grease your bolt lugs to help prevent galling the lugs. Below there is nothing wrong with a few thousandths head clearance. The ejector will push the case forward in the chamber along with the firing pin hitting the primer and this reduces the load on the bolt face, locking lugs and the amount of dwell time and bolt thrust.
