I'm trying to identify two 9mm headstamps. One is marked FC 20; I know FC is Federal, but I have not seen anything about the 20.

The second, almost looks Arabic or something, image below. 

FC 20 would be coming out of the lake city plant with the year stamp. 

FC with a year denotes military surplus for any nato cartridge. 

 

Edit. The one posted is a browning cartridge, that  is their logo.

Yep, Browning.

It took me a minute of spinning my phone around in circles until I noticed the antlers. lol. 

I have browning stickers right on my reloading bench, among others I constantly see.

The Buckmark logo can be seen on the rear windows of about half the pickup trucks in America.  You have seen that logo many times, but probably never registered because you don't own a Browning....  Commie.

If it had been the full logo, I'm confident I would have been able to determine what it was. When a logo is so small (and incomplete) it can double as a Rorschach test, some marketing people didn't do their jobs well. Even worse, the engineers didn't fight hard enough against the marketing people telling them it was a bad idea.
