Thread: Neck Length vs Pressure & Velocity

    Default Neck Length vs Pressure & Velocity

    Since I have recently been experiencing the unusual phenomina of shrinking cases instead of growing cases, a question has come to mind...

    What is the effect of longer or shorter neck lengths on pressure and velocity?

    More or less, Neck Length, should effect Neck Tension, which should effect both pressure and velocity, but I shouldn't think it would be enough to matter much.

    I think I read somewheres that a shorter neck gave more consistant neck tension compared to a longer one. I dunno how true that is? It was a mathmatical calculation.
