LC is from the Lake city plant, it is military brass and would need to have teh primer pockets chamfered before reloading. FC is Federal, and it could fall intot that catagory as well. UMC is Remington/Un ion Metallic Cartridge, and is comercial brass. WCC is Winchester Case and Cartridge, it could be military or commercial. PMC, is PMC from Korea, usually loaded as commercial. TW, GFL, TW, TZ is mixed military stuff, think some is Israeli. Think the BHA is from Black Hills.
Don't know about the others. Think one of those headstamps was on some Guatamalan stuff I shot.
