Now i know why?
If you look at the photos, the brass makes its own donut using standard FL dies. The case neck wall thickness gets thicker closer to the shoulder.
To get rid of the problem of over working the brass & making it work hardened, i now outside neck turn brass for the standard die.
A bushing die would not have this problem, when pulling the expander thru the necks. The bushing does not need to size all of the neck.
Or hone out the neck of a standard die. Have done this also.
Or anneal the brass every loading?

Has this been a problem for you? I use RCBS dies.
