[QUOTE="woods, post: 403764, member: 6042"] Hey tlk, the question you are asking would make more sense if you are talking about a bushing die than the Lee Collet. For instance you say your mandrel is .3055" and can get the ID to .304" with varying the degree of effort on the press. This should not be possible. You should not be able to get a varying degree of ID regardless of the amount of force you apply, all you are doing is putting more stress on your die and press. IOW the Lee Collet mandrel is a certain specific diameter, you are not going to compress it smaller, so the ID which is pressed against that mandrel can not be smaller than the mandrel. After pressing the neck brass against the mandrel, if there is any springback, that springback would add to the ID of the neck. Now if you are taking the mandrel out of the Lee Collet and resizing I have no idea how small the collets would squeeze the neck since there would be no viable reason to do so. And the case neck thickness has no bearing on ID when using a Lee Collet but it has everything to do with a bushing die used without an expander. That is the only time I have talked about removing the expander/depriming rod is with a bushing die. IMO that is good and the way to do it. It would make no sense to spend extra dollars to get an expensive die, buy the bushing to a specific size and then re-expand to another dimension. That is what a regular FL die does. IMO consistant bullet release is one of the factors in low velocity spreads. How much is certainly debatable and results are not always consistant. IOW my velocity spreads have lessened across the board for all my loads but they are not always extremely low. There are other factors, some of them uncontrollable, that will all add in. Is it worth the extra time, effort and money? For me it is because I enjoy the results. Each has to make his own decision. [/QUOTE]
