I think it is Lake City.

WCC is a winchester/western cartridge co. military headstamp.

thanks!

Right, and the date’s there, too, so these look like WCC (20)10 and WCC (20)11 headstamps to me.

6

That’s my read too.

Winchester military '10 and '11

I’ll further guess that it is M193, as it lacks the NATO circle cross on the headstamp.

thanks guys!

I agree with the Winchester.

This is lake city 5.56 brass I loaded that I got from Natchez:
