Help identify this .223 cartridge

[VUPDblue]

Anyone know what this round might be? I have a handful of them, don’t remember where I got them, and they were loose when I acquired them. Headstamp says .223 and what looks like a question mark. The tip is black. I have zero other info but would like to know what they are.

Apparently a large batch of ammo from Bosnia was imported with black tips and that head stamp. It is basically SS109.

*edit*

Internet says the flash holes can be small which makes reloading a bother.

The character looks to be arabic, possibly. Could just be a company mark.

What BBI said. Steel core AP.

Now the real hard part. What to test them out on?

Don't forget the camera.

Headstamp looks like Infidel in Arabic script.

Thanks all. I didn’t figure they were anything special, I just couldn’t find any info on them.

The known.
That is an Ingman headstamp.

[STRIKE]The unknown, without dissecting the cartridge.
About 15 years ago, Bosnia shipped a lot of their M855 to America. Igman is a Bosnian NATO contractor. The claim was that it tested 12fps too slow for NATO spec. It's believed that actually the neck size is out of spec because people who bought the surplus ammo were having issues with the cartridge getting stuck in the barrel.[/STRIKE]

I found this on the M14 forum.
For awhile , there was some Bosnian/Ingman SS-109 going around with black painted tips.

Give em flight downrange on some steel and watch the metal splash. Ah! All better!!
