Late Uncles Inland M1 Carbine. Still teaching my boys.

[KneverKnew]

Pictures of milsurp case heads we shot in the carbine yesterday. I think they are all non corrosive. My old question is about the LC 52. How can you tell if ammo with that head stamp is genuine LC or from China?
If there is even a doubt as to corrosiveness, I will clean with water.


I will upload pictures of the other milsurp case heads I have for verification as well.
