[QUOTE="sestamibi, post: 3064179, member: 67732"] So if I understand you correctly, the friction or interference fit of the bullet when seating has no direct relationship (if any) to neck tension, which is related to springback. The bullet does not move until [I]after[/I] it is released by cartridge ignition and the walls of the neck expand outward to the chamber wall. How quickly the neck releases the bullet is related to springback (ie tension), which determines the timing of this release. So whether I have 4psi or 40psi on my hydro press really is of little consequence in this process. Maybe if there were some "hoop strain gauge" that could actually measure neck tension or springback I could get a better understanding of what my brass is doing, but I don't think there is one commercially available.
