These are the worst 2 of 8 30.06 rounds that were in a buttstock ammo carrier for many years.
Probably after a wet hunt and neglected.
One has been lightly steel wooled, the other not. It looks like rust but its not magnetic.
They are not as deep as the pic makes it look. Its hard to feel it with a thumbnail.
I have not shot the rifle in years.
What are your words on these?
