Does anyone know what all the purple blobs are on the newer federal 215 primers are? I picked up a case and dumped 40 out in a tray and there is purple crap all over half of them and traces of purple on the others. I got out a box of older 215 s and there is no purple on them at all, just the red like the 210s. The inconsistency of the purple got me worried so I did not load them. Should I have any concern.
