Neck Die galling 223 brass

I got a new box of Lapua brass(cardboard box) but at some time it has been dropped on one corner.With my new Hornady neck die I thought I would run them all through.even tension,round up any ovals etc.Using Graphite powder and #7 shot I set to.At 40 I noticed the necks were galled,starting at around 10 and getting worse,I stripped the die and cleaned with a bronze bore brush,still doing the same.
with full length dies I always use Lee lube and have no problems with any cal.for years
Have I got a stuffed Die?
Have I got 30 stuffed cases?
Have tried to take a photo but they don't show the marks,vertical galls the full length of the neck.can be felt with thumbnail when rotated.
Thoughts please anyone.

Been there done that....
Take the die apart polish off the brass stuck in/on it.
You can see it stuck to the die.....
Then use different lube on the necks, otherwise it will just keep happening.....
The lapua neck is quite soft & scratches easily...
The brass will be fine after a couple of firings you won't see it :)

Brake cleaner with a Q tip helps.

Autosol, a soft rag and some elbow grease will do a good job too.
