My research and use shows different, all my CX2000 primers I have bought, both yellow box and the new blue and pink have red sealer over the flash hole. I purchased a bunch of Kent salvage hulls that I either used for short shells or salvaged primers and they have both black and blue sealer on the primers. Honestly I couldn’t find any pattern to them, same shell would have both colors. On Kent’s website they state they use Cheddite hulls and CX2000 primers in all of their shells.
I also buy new primmed cheddite hulls from Ballistic Products listed as having CX2000 primers and they have blue sealer.
