Regarding the photo with a number of boxes, I can comment on a few:
Bottom row, from left:
.38 Colt Super Automatic cartridges, which are a hotter version of the original .38 ACP. I assume your last two photos show the contents of this box.
Middle: 2 Hungarian boxes of Hungarian M31 military rifle cartridges. The same type was used by Austria under the designation M30 S. (Adoption 1931 and 1930.)
Right: No. 26 primers for Cal. 30 cartridges
Second row from bottom:
.276 Pedersen cartridges as intended for adoption of the first self-loading rifle by the U.S. Army. The rifle designs by Garand and Pedersen competed. Due to intervention by, in my view ill-informed, Gen. MacArthur, the .276 was killed and the Garand, changed to fire the existing .30 caliber cartridge, was adopted as M1.
Middle: Cal. .30 bullets for the cal. .30 M72 Match cartridge. These were dimensionally the same as the heavy, boattailed M1 cartridge, which was adopted in 1925 to replace the older M1906. The M72 bullets were much later also used in the 7.62 NATO M118 sniper cartridge.
Right: 7.65 mm long cartridges for the French pistols (and later submachine-guns) adopted between WW1 and WW2. These cartridges originate from the U.S. cal. 30 M1918 “pistol” cartridges, which in reality were planned to be used wih the secret “Pedersen device” to turn a M1903 rifle into a short range weapon capable of semiautomatic fire. (The same designer Pedersen as mentioned above with the later .276 cartridge.)
Apart from the leftmost box in the next row, I cannot really comment on the others. This box contains cartridges for the British .455 Webley automatic pistol, mostly used in the Royal Navy (WW1). Because the British Army used a revolver firing a very different .455 Webley round, the rubber-stamped text was deemed necessary.
