[QUOTE="Old teacher, post: 855848, member: 48420"] What advantage do you gain by FL sizing and then NS? Once you have run the case through the FL die, the neck has been sized. The whole point of just neck sizing is to create a case that exactly fits your chamber. If you stretch a case to the point that the bolt has trouble closing, then you bump back the shoulder about .002. Full length sizing merely creates a case that the die manufacturer may or may not have created to match the "official" specs of the case. "Not" is most often the situation. I have had to send a half dozen or more dies back to the manufacturer to be adjusted to be the correct size, and then the case may still, or rather will not match your chamber. Neck sizing guarantees that your case will exactly match the chamber of your rifle, and the only issue is stretching cases requiring the bumping. Since a neck sized case exactly fitting your chamber has no where to go when it tries to stretch, bumping the shoulder back on a regular basis makes neck sizing a moot point. You have lost part of the advantage you have tried to gain by neck sizing in the first place. I have never had to bump a shoulder back in my life,, but you do need to make sure you keep your cases trimmed to the proper length. I not only do not bump shoulders back, but I set my neck sizer so that it leaves about .002 or .003 of the neck unsized. Even doing that, I have had no problems closing a bolt.
