Federal champion red box.
These are older but stored in GI surplus ammo cans.
Pulled some out and noticed the spots.
Then I went back further into some newer ammo squired at a later date and it has the spots. Checked other brand ammo and none are like this.
It's almost like colorfill but I'm not sure.
Odd that only this particular ammo is showing tarnish. Everything I have is stored in same spot in similar cans.
