My redding 308 die is sizing the brass down at the .200 line from .472 fired to .470 sized. Is this working the brass too much? Brass has 4 firings on in and is now getting hard to resize and is shiny near the base after sizing. Shoulders and necks size fine as I anneal every firing. I noticed a slight click on some of my brass at the top of extraction during the last match which has not happened before on this gun.
