[QUOTE="QuietTexan, post: 2447144, member: 116181"] Yup. 👍 Crimp =/= neck tension, they're two different things. Neck tension plateaus at the point the neck starts yielding. Crimping is mechanically deforming the neck permanently the opposite way, and requires work to overcome, hence your in-case pressure spike to pierce a primer. Velocity will increase to a point then stop increasing because there's no tighter the neck can grip. With a crimp die you can keep increasing pressure until you make the chamber a bomb by deforming the billet with the crimp. [/QUOTE]
