I am sure somebody will enlighten me very quickly on this subject! Picked up nine WW2 50cal Browning cases over the weekend and on giving them a clean one appears to have a very different type of primer to those I have seen many times before. From external appearance it appears to have been modified and has the pattern more like an electric initiated primer, although I cannot see any insulation around the white metal circle. The strike is also much lighter than you see on the usual percussion primers. Was there any difference between rounds used in aircraft weapons to those used on ground guns?
