It seems Navy 40mm Bofors cartridge cases are the most common WW2 dated case you run across here in the US. I believe I have seen war dated cases marked as "MKI" thru maybe about "MK5 or MK6"???
I know almost nothing about Navy ammo - can someone enlighten me as to what the different WW2 bofors case MKs are and how they differ from each other?
