[QUOTE="LRHWAL, post: 377525, member: 5418"] Sorry to ressurect this, but I've been away and as I was hunting I figured you may forgive me... MikeCR, a question for you please and anyone else who wants to chip in... Okay, so I hear you, the neck expands before the bullet moves. The pull force would in my opinion (theoretically?) determine the "dwell time" or contribute to it. So if the internal neck surface creates more friction, then the dwell time may be a little longer. Also, the internal neck surfaces should ideally be pretty similar to ensure consistency in performance. Your thoughts? As an aside, I don't suggest that a smooth surface has less friction than a slightly rougher once cleaned with a brass brush for example as opposed to one that's polished, as the surface area actually contacting the bullet jacket may be less with a rougher surface, but this isn't relevant for my purposes, so I haven't really thought about this much. Thanks for sharing your thoughts. WL [/QUOTE]
