I am reloading 7 PRC using Hornady Custom FL dies. After my 2nd resizing , loading for 3rd time, I noticed some vertical buckling of the case neck as shown in the picture? Didn’t happen on first resizing. These dies are new, less than 50 rounds. Is this caused by a build up of case lube on the neck? Is it safe to shoot? I’m gonna clean my die body and try another round. I am using some older Hornady Unique Case Lube. Never had this issue before loading 300 Win Mag for years?
Dimpled case neck after sizing?

What he said.
Yes ... it should fire-form back to normal, and then resize with less lube ... also helps to anneal first.
