To me the primer looks like it is covered with wax or laquer, Is it?

It could be wax, might be someones idea of waterproofing it, Could be the lubrication from another round has sstteled on it, looks like it’s in the headstamp too. It’s not factory.

Just had an e-mail saying he thought it was glue & from being glued to a board.
