[QUOTE="boomtube, post: 383646, member: 9215"] "...they leave verticle pinch marks in the neck of the case. Is this normal?" Yes, it's normal. It's really not a "pinch mark", what you're seeing is where the collet jaws didn't push and that leaves slightly raised pads, sort of a "non-pinch". It's meaningless but you can give the cases a tiny turn and size them again to push those raised pads down. "I sure didnt like it as I feel it would be a good place to start a crack." That's not been a problem for me and I've used those dies for maybe 12-14 years. In fact, part of why I like them so much is my cases last significantly longer without splitting than they do with any "normal" sizer design. And my sized necks are quite a bit straigher too; not perfect (that's unobtainable with most cases) but significantly better on average. So is accuracy. The Lee collet neck die sizes the necks against a straight, center mounted steel mandrel that's slightly under bullet diameter. All necks end up with the same insided diameter (often refered to as bullet "tension") no matter the actual thickness of the necks. Bushing dies can only make the outside of the sized necks the same and have to use an inside expander to make them consistant. That inside expander ball is THE thing that causes most neck non-alignment/bullet runout. [/QUOTE]
