Dimpled case neck after sizing?

[rmiked]

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?

Ok to shoot if it chambers fine?

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