Found some brass cased 5.56mm 55 grain FMJ ammo that I forgot I had.
I've had it for roughly 11 years and don't know what it is.
I don't know squat about headstamps or methods of crimping primers, so I will describe and try to illustrate what it looks like.
The primer has three small indentions around it's perimeter at 12, 5, and 8 o'clock .
There is the number 87 above the primer, and 13 below the primer.
Looks kinda like this:
Any ideas? Would like to know what it is before I shoot it.
