Was going through some old cans of Talon .50 bmg today and found this. Yikes. Can it be buffed out?

I'd probably just shoot it I had a feeling it might be Talon when I read the title.

Just shoot it, that's nothing.

If you want to see tarnished, find some old DAG 308.  100X worse and still shot fine.

Yeah, just shoot it; purely cosmetic.   If you have other BMG ammo, you'll probably want to shoot this stuff up first, though.  This stuf isn't going ot improve with further age.  You might also give some thought to storing all your ammo in low moisture environments - HD plastic bags, ammo cans, etc.

Pull the bullets, wash the brass. Reload. I wouldn't shoot them.

There is way too much pressure in there for me to trust them. And I do not want to end up like Kentucky Ballistics.

These are the danger zones:

Looks like most of what you have circled is sealant that wasn't cleaned off but I can't tell for sure. I've never seen compromised ammo blow up it usually just doesn't work. Obviously that's not a guarantee but the Kentucky dude had a messed up probably fake SLAP round so it's not really the same.

All my other 50bmg ammo looks good. Just two cans are like this (300rds)

Its the seam ring to chamber the round. That where when I see degradation I worry.

I have never shot 50 professionally so consider my advise as a mild warning.

I can only imagine the condition of the ammo in the ME

I had a customer call me from the range, told me his M82 went click and had a live round in the chamber and he could not get it out. I told him to whack the bolt handle and see if that works and it was stuck. So he brings the IED (lol) to me. After sweating a good 15 minutes and waiting on the big boom I finally got what was supposed to be a live round with a primer strike out and it was empty so he didn't realize it fired. The moral of the story is that is was corroded and looked just like yours and it stuck in the chamber. I personally would not shoot that and do as someone above recommended and reload them.

We use d to take ammo that was pretty grungy and wrap A bit of red scotch brite around it and twist the round in the scotch bite bad. Cleans grit and most corrosion off  pretty quickly.

Talon was the only ammo that choked my 82. Round would stick and cause a cascade of problems.

First the extractor does it’s job and rips part of the rim off with style. Then It would pick up the next round and attempt to chamber it which is obviously an issue. Ended up totally bending the bullet in the neck so you end up with one loaded round hosed and one piece of brass hosed. Thought it was a fluke but did it 2-4 times and that was it for me as I’m not a fan of the cleaning rod extraction.

I suspect it’s a sizing issue because my 99 ate them like candy but my Safety Harbor they are a tight fit when closing the bolt and opening after firing. Moral of the story is that the 99 is a rock star.

Stopped by Harbor Freight today to pick up some stuff and grabbed a 6" buffer to try to clean up the brass.

This is the result

I’m such a weenie I don’t think I’d feel right holding the round and using the buffer but they came out nice. If it really bothered me I’d just tumble them I think.

Buffing them they do get a little hot and I thought about "what if this thing explodes in my hand?"

Pull a couple  and check the condition of the powder and inside of the case.  I would also put the empty case in the rifle and  fire it to see if primer  goes bang,
You cleaned the outside of the case  but still have no idea if any corrosion actually get inside of the case.  Also make sure whatever you’re using to pals the case does not have any ammonia in it it will start to weaken  at the case

Wasn't there a bad batch of surplus 5010 floating around when Talon was around? I heard it broke down and corrosion would be an indicator or smell bad if still in the can.

I had a bad lot of Talon from Sportsmans guide years ago. It was oversized and the shoulders were set back quite a bit compared to the others. I didn't notice and had a failure of some sort but I don't recall what.

We got a bunch of Talon at Barrett years ago. Some of it was seriously overcharged or so underhanded it would open the 82a1 action about an inch or so.

In my younger (and slightly dumber) days, I filled my cement mixer after removing two paddles with red Lyman tumbling media and turned it on. While "tumbling" I slowly dumped in 3 50CAL ammo cans of loaded Talon ammo and let it tumbled for a day or more (outside due to dust generated and for safety in case one fired). Then the contents were dumped thru a large screen to separate ammo from media. Hand tumbling in a large pool towel removed the dust from the perfectly shined cases and projectile tips.

This ammo was then fired in my stock AR-50.  As stated elsewhere, I fired 3800 rounds of questionable ammo thru my stock AR-50 wearing out the almost smoothbore barrel.

Then I learned to reload the 50BMG cartridge.

Then I learned to reload the 50BMG cartridge a bit more accurately.

Then I learned to reload the 50BMG cartridge a little bit more accurately.

Then I learned to reload the 50BMG cartridge a much more accurately.

Then I learned to reload the 50BMG cartridge a lot more accurately being able to shoot 4" 5-shot groups at 1000 yards dependent on wind conditions. The rifle also went thru modification and learning processes  involving 3 more K&P SS 1.75"dis 416R barrels 34, 36, & 38" in finished length with multiple twist rates of 1:15, 1:14, and 1:12 being tested. Future barrel will be 38" finished with a 1:13 twist and a custom chamber.

Buy a power precision 50bmg shell holder. It has a hexagon end on it to chuck into a drill press.

Throw some polishing compound on a rag, hold on tight, and let it spin.
It’ll clean right up.

There is a video out there that states that if you tumble a round you are breaking up the inner gunpowder into much smaller pieces.
Smaller pieces have more surface area essentially turning the gunpowder into "bullseye" or other fine powder type.
Which means EXPLOSIVE force.
Makes sense to me.

That has been repeated as long as I've been a shooter. The issue is that nobody ever seems to be able to back it up. Factories tumble loaded ammo.

Red scotch Brite pad. Hold round by the base. Wrap scotch Brite pad around kind of loose. Rotate the round kind of fast. It will remove the tarnish pretty quickly.

Did it to a lot of rounds in the past. Works fairly quickly.

Oh......Now ya` done gone and done it.

I pulled apart several rounds for a buddy years ago.

Those Bastids were green on the inside and some even had loose cores that you could hear rattling when I shook them.

OP, If you want your rounds clean, just grab some burgundy colored ScotchBrite and rub a little bit. That is what I would do and "Let `em fly".

I have been tumbling loaded ammo for years. I did it to get the case lube off in corncob. I have even tumbled rounds made in the 50`s to shine them up.

NEVER had a problem yet.

I agree with your statement Sir.

All of my rounds when fired through a Chronograph after being tumbled, are very consistent in speed and accuracy. ( Accuracy.......Providing that I do my part when the hammer falls )

I'd use brasso and polish by hand.  Using a power tool could heat the powder to flash point if old.  Be careful man .

I bought a few hundred surplus rounds from Copes a few years back. Not Dominican but dont remember. Foreign though.
Not just tarnished but wet green corrosion some through the metal case. Those I toss.
Because I'm a cheap bastard I clean them up with scotchbrite, loaded one into a weighted down Steyr, and pulled the trigger via a rope.
Fired just fine and extracted fine too. I looked for any indication of overpreassurization; nope.
I'd say 25% dont fire off though.
