M1 Garand Ammo Question

[diametrik 7]

Hello, looking for some advice and guidance.
Got a bunch of Military Garand ammo in clips with K A on the headstamp, years vary, 70 71 or 72
Where can I verify source of manufacture, is it berdan primed, corrosive ?
Thanks

According to the headstamp guide, it is made in Korea. I think it is boxer primed, but don't know if it is corrosive for sure.

The Korean K A is corrosive. The Korean P S is not. Boxer primed.
