just for kicks and grins you might want to shine a light down into the case to see if those are Berdan primed.
Not Berdan primed but they are sealed in with some kind of red sealant...and of course crimped.
I used to have pinch & arbor bench deprimer, but its long lost in a former move.
These 75 or so spent milsurp 50-year-old 30'06 brass, really aren't worth the trouble to buy another,
clean and remove the crimp

I prolly drop them in the scrap barrel for Boy Scouts fund drive.
