Hi, I read the post about case necks tightening up when left over a period of time.Here is my ?. I prepared 20 Lapua 6mm br. cases,weighed, wall thickness, lenth and ran them thru my Redding neck bushing die using a .268 bushing,,I also have a .266 and.267 bushing) I then put them away for when i find that right load combo.Bullet, powder, and OAL. When i do decide to load up should i run them thru the neck bushing die? I have the Reddind comp. die set with the body die.
