[QUOTE="dok7mm, post: 2074033, member: 90080"] It is the diameter of the case you are compressing. That brass has to go somewhere when your die is a good bit tighter than your chamber, only place is into the neck length. If you know what your chamber neck length is and your trim length, you should see if the neck is moving forward excessively with each firing. That is an indicator of what I described above. Softer brass, higher velocities and a tight die/looser chamber all contribute to this, if I'm correct. OR, you might change your lube! [/QUOTE]
