Those that shoot a lot of Short Range Benchrest, especially the PPC, run into this as a common happening. When you shoot loads that push a 68 grn bullet at 3400+ FPS, it’s going to happen.
I borrowed an idea from Charles Huckabe that does cure it, for several firings if you are willing to do it every time.
Basically, it is just a Redding Body Die with the shoulder bored out. All that is left is the tapered part that sizes the body. You use an arbor press to push the fired cas in flush, flip the die around, and push it out.
this does away with the shell holder, and allows the die to work better on the web of the case.
the trick is boring that shoulder out. I use a carbide drill, then a carbide boring bar to make sure.
Sometimes I will get a click after just 4 firings. This allows me to keep the brass going..........Until the primer pockets finally give up the ghost.
