I recently bought a few hundred rounds of mixed headstamp 5.56 ammunition front a tenant. I'm trying to figure out what it is. Some of it was easily identifiable green tip. Some had a RORG headstamp. IMG_0008.jpg

I googled it and it appears to be British SS109. Am I correct?

There's was also some LC headstamp without the tip painted green.

I'm not sure what this is. Can anyone shed some light?

TIA.

Edit: Sorry but it looks like I reversed the pictures.
