I received my 720rd case of Swiss surplus from ammoman (super fast service), and noticed that the upper 1/3 of the brass is a bit discolored. I absolutely do not care how the stuff looks, as long as it shoots ok, so I wasn't worried about it (I have not tried shooting it yet).

However, in reading through some previous postings here, I saw several references to tarnishing, and the context indicated that this was undesireable.

Is these concerns merely cosmetic, or does tarnished brass indicate some other problem with the cartridge?

As long as it's simply a tarnish in the finish verses a build up of corrosion, it is strictly cosmetic and will not affect function.

Good luck!

Nothing to worry about.

Read: Ammo FAQ

Edit: Unless its got barnacles crusted all over it.

Suspect what your refering to is the annealing process, which is done to most mil-spec ammo, (heat-treating to harden the necks of the brass).


What your seeing is annealing.

Thanks for the information... this make sense.

(p.s. – I did try the FAQ first, but instead of manually scanning through, it I merely searched for "tarnish", thinking that's what the discoloration was. If I would have taken a few moments to read through the questions, I would have spotted the "discoloration" question. Doh!)
