I have seen Israeli-produced Winchester Q-loads (white box), but was not aware that any of the Independence was Israeli-made; thought it was all loaded by ATK.
Can you post a pic of the packaging?
Isn't that discoloration just from the annealing process? I have noticed all my factory new ammo, all my 5.56 NATO is annealed show that discoloration but none of my .223 REM is discolored.
