I have a bunch of used .223 brass.

Most of them so far have FC stamped on them.

Some have a number after the FC.
FC10, FC 13, FC18

What does the number represent.

The year of manufacture. Those would be 2010, 2013 and 2018

FC 10 means it was made in 2010 by Federal, same for 13 and 18.

Federal currently has the Lake City contract for U.S. Military small arms ammo. It could be cartridge cases made at the LC facility and those are a 5.56 production over run. I have loaded some of those cartridge cases and they compare in weight with Lake City (LC) cartridge cases which are thicker then commercial 223 cartridge cases. I have tried for a number if years to confirm this, but Federal is tight lipped about this. Also if it is LC production cartridge cases, the brass should have a higher % of zinc alloy making the cartridge cases slightly harder. I have observed that LC and FC head stamped cartridge case take more effort to resize with small base sizing dies.

FYI. Winchester won the latest contract to over see Lake City production with a seven year contract with an optional three year extension if Winchester wants it at that time.

The head stamp say Rem .223.

FWIW those are crimped primers too. When you press them out go slow and they will pop out.

FC military brass is very good quality. Remove the primer crimp and you may find it to be your favorite reloading brass.
