Just remember that when you polish out a chamber the same die becomes more "aggressive" by the amount that the chamber was enlarged at its base. You may not need to change the die.
Another thing, there can be more than one factor involved in the creation of a click, so when fellows write about different solutions to what seem like the same problem, because the symptom can come from more than one situation, they are all right, if their particular fix worked for them, but they all may be wrong to the extent that they are not aware of other related but not identical causes. For example, I have a Vari-Base die, that I can use to cure a click that a standard die might not. With the shoulder bump set to .001 from max. length, I can have a click on old brass, but if I unscrew the base insert just a little so that the die has more reach on the case, that, in combination with a shell holder that has been turned down around .014 gets rid of the click. Another factor is that the bottom of the inserts have much less of a radius than any one piece die that I have seen. Some dies, that are currently available, the Jones for instance, adjust the shoulder bump in the die, rather than by moving the entire die, this allows then body of the die to be set as low as the shell holder will allow for all bump settings. The Warner die may also have this feature. I have not played with one, but I seem to remember that it does. Perhaps someone who has one will speak up on this point. A long time ago, I did an experiment with a case that had a click. It was well used at high pressures. I removed about .002 from its OD. parallel with its CL,starting at the top of the extractor groove. This solved the problem. On my next trip to the range, I repeatedly fired the case with hot loads but within that number of firings, the click did not reappear. Knowing what I do now, after playing with the die's base insert, my problem was that the die did not reach as far down the case as the chamber did. The difference probably being very small.
