As said in a earlier post this came out of an attic in a uncovered crate with some other .50 surplus. I delinked it and rubed each round down with a rag with WD-40 in it to get the dirt and rust spots off. There are 71 rounds of which 14 are tracers. Would it be better to sell the links seperate? I added one to the picture to show which style they are.

They are probably worth a couple bucks a piece if they still work. I would pull a couple of projectiles and see how well the powder and primers held up to being stored in an attic for years. That is one of the worst places to store ammo with the big changes in temps and humidity. That stuff was getting over 100 degrees at one extreme to below zero at the other.
Some one gave me a box of .32 auto that was 6 years old and stored in the attic for safety reasons he said. I tried 7 rounds and none of them went off so I threw the box away.

Don't use WD40 on ammo, it will kill primers.
You might be able to get $1 each, let the buyer know how it was stored. I would be surprised if it was any good and would only use it for components after checking the brass to be sure it was good. Toss the powder and primers, reload them if the brass isn't brittle or has corrosion that goes into the brass.
If these were broken down for components would the projectiles have to be resized?

Box O' Truth decided otherwise... but I have seen some .22mag that fell into cooking oil that then had about a 40% failure rate. Saw the .22mag failures first hand.

Oil can kill powder (makes it not ignite completely) but as BoT says, WD40 doesn't kill primers. I've done tests with all sorts of things trying to kill primers.
More to the point, a light wipedown will not hurt a .50bmg round in the slightest.
