New, Old Stock RP Brass - Long Term Storage Reaction?

[iShoot17]

Hey y’all!

I have a question regarding something that has me stumped. I recently bought some new, old stock brass. When I got home to open up the boxes, I noticed that things just didn’t seem right. The brass was colored, blue and purplish. I have never seen something like this before with new brass. They almost look like the whole case was annealed? It was stored in the factory Remington 20 pieces styrofoam cartons, and pushed in to the point the cases were slight difficult to remove. As you can see in the pictures, most cases have a straight line across the point to where they were pushed into the styrofoam. I’ve never seen something like this. Was there some sort of reaction?

To answer one question beforehand:
I have not tried washing the cases, yet. I figured I would check with y’all and get your thoughts first!

The first picture shows how the brass came out of the Remington box, still in the styrofoam. The second is all 20 cases set on my bench. What do y’all have to say about it? Wash and shoot? Shoot as is? Take them back?

Thank you for your time!

I guess it's your decision to clean them or not but they are still OK to use. That is indeed tarnish on the brass. I have purchased some like that in the past that were stored in cardboard boxes with dividers.I chose to clean them with SS pins in a tumbler because I like the bling.They have gone through many reloads (308 WIN bolt rifle) with normal case life so far.

I would say it's a reaction with whatever lube the factory used. Strange that it did not migrate to any of the heads. Which is why I would use them, having already destroyed some brass on an electric induction range while trying to dry them. In that instance, the body and heads were all a nice, soft, purple. In concentric rings, in the glass dish they were in. Some weren't too bad. They all had to go.

I now bake cookies after I dry brass, as they cannot be done at the same time. (Oil vapor from the cookies on the brass.)

You bake them, really?

I just eat the dough.

Saves time.

If it makes you feel better clean them and it makes it easier to find in the grass at the range.
After you size them and possibly trim them you might give them a quick tumble anyways.

Safe shooting, Mike
