Here is the website for the collet die Innovative Technologies - Reloading Equipment
10-15 reloads is pretty good. The base of the case will be work hardened, hence why it is not staying at .511 You can/use to be able to buy a collet type die that would resize the case just in front...
How many reloads have you done? Might just be time to bin.
