OK. I give up. Where is the Lot # located on a box of CCI 400 Small Rifle primers? It's a new blue and silver box of 1,000.

Look on the individual boxes inside.

Nope, not there either. I have 2 boxes of 100, one older, one newer. The old one has the lot# in the lower left hand corner on the back of the box. The newer one has a large crown symbol instead.

It is embossed on the front of each 100-pak in the silver area...should read something like "B25H" or whatever the lot number is.
