I was picking up range brass lately and while processing it i notice on the head Stamp 5.56 NT  I found lots of LC And IMI  Winchester ,WIN 5.56, fed And Rem Brass All With Crimped Primer Pockets. All Clean And Ready To Process

I Have Not Seen The 5.56 Nt Stamp before Just Wondering

Thanks Superfly

Non-Toxic, I believe.

Ya know, mercury-free primers, no exposed lead on the bullets, etc.
