Headstamp help...

[ZombieKiller]

Hey guys...


I picked up some ammo in a trade (7.62 x 51). I do not know how to read headstamps...

Could somebody help me ID these please?

fc 61 - has the NATO cross in circle
LC55 - has the NATO cross in circle
WRA 60 - also has the NATO cross in circle

Also, how do you read them so in the future I can tell what is what....I just do not want to end up with corrosive ammo...and is any of it reloadable..

Thanks in advance for the wisdom...

I'll take a stab at it

FC= Federal Cartridge
LC= Lake City
WRA= Winchester repeating arms

LC55 is Lake City 1955
WRA is Winchester Repeating Arms 1960

In general, the letters denote the plant and the numbers are the year.
If it's boxer primed brass, you can generally reload it.
