[QUOTE="whatnext, post: 2328867, member: 110234"] I run a Wilson mandrel on new brass after inside/outside chamfering, load and shoot to fire form to your chamber. This irons out any imperfections that developed during packing/shipping and in your case, will get you closer to desired neck tension without jamming a bullet in an undersized neck. Mandrels run smoother if you dip every second or third case mouth in Imperial Dry Lube. I believe the Wilson mandrel is -.003”. After that go back to your normal reloading program. [/QUOTE]
