Federal 210 Primer color variation

[MacCoon]

I opened a box of federal 210s and flipped them and immediately noticed a distinct color difference. I tried to document it with a couple photos. if the red material is the fuel for ignition then I can’t expect anything other than a proportional variation in powder ignition.

The sort resulted in 4 groups. See pics.
I kept track and sorted loaded rounds so I can measure velocity … will see if there is a gross difference.

Haney, tnx for ur reply. I see the terminology in the graphic indicates ’foil paper’. The redness on my primers is definitely not a sheet material … it appears to me to be a dried liquid. Perhaps it is a sealant on top of the foil to limit moisture from absorbing into the priming mix beneath. If you zoom in on the pics you can see the red material covers the brass fingers, (3) surfaces, on all edges on some and none on others.

I dont think I have seen foil paper on any currently manufactured CCI or Federal primers.
That red paint is probably some part of the manufacturing process, maybe an inspection
mark as there is no consistency in the application of it.

Might get an answer by reaching out to Federal Cartridge here in Minnesota. I use to call on the engineering and maintenance group a few years ago and would definitely asked the question if I did, but I am no longer working for that company.

The red on the primers is a latex identifier and does not affect the performance of the primers.
