Tried to post a pic but can't.
Old box of Dominion cartridges.
Says 30 SPRFLD But has the word PNEUMATIC just as large under it.
Drawing of cartridge on box with :

DOMINION
30 Springfield
PNEUMATIC HIGH VELOCITY

Drawing of cartridge shows a hollow point bullet loaded in it.
Also states Winchester Remington Savage Mauser Mannlicher and Gibbs rifles

What was meant by PNEUMATIC ?

Well that explains it , no need to use them , so they survived.

Great response!
Wonder how they even wound up there? Long way to bring something that will not be used. And nothing there gets thrown away. All re-purposed.
Also that's where I learned about seal oil as a lube in crazy low temps.
