Parashooter: Your picture is worth at least a thousand of my words!

But, in the unlikely event anyone can find a Vihtavuori outlet that sells more than the usual Boxer-primed goodies, what the truly keen seek, are:

"Kemira Oy" (I'm told that "Oy" means "company" in Finnishicon).
No3, 5.5mm(.217") primers.

They come in "sleeves" of 250 primers, packed 10 sleeves to a small, white, carton.

By the way, what bullet and propellant load are you using in your reworked cases?
