Thread: Case Sizing Dramas

I am putting little dents in the case necks when FL resizing. From what I read it could be due to a build up of case lube in the sizing die. I have tried soaking the die in white sprits/petrol to clean it out but without success. Also tried changing from a lube pad to spray on lube but no change.

It is now happening in 2 sets of dies; -308 and 7RM, both of which are cheap Lee RGB dies. I have a reasonably light rcbs press which may be part of the problem. The thing I don’t understand is that these dies have a relief outlet where excess lube escapes during sizing. Perhaps some rubbish is stuck in there?

Any clues on what i should be doing differently or how to fix the affected dies?

Thx Ross
