Not looking for a huge discussion on it since I know it's probably been beat to death several times, but I came back home after being gone for several months and realized I completely forgot where my different brass piles came from So I have about 100 pieces of this FC brass that I don't ever recall seeing, it has the 3 dots around it kinda similar to LC brass. Anyone ever use this particular headstamp, any problems with web thickness? I've used the headstamp on the right several times, have about 200 pieces of that, that I will probably use since I do know all of that is the new stuff once fired from my buddies ar.


The headstamp on the left is the one in question.

Have the same stuff. I belive its just like numbers on golf balls. Its if your shooting with a buddy and both keep your brass you will be able to sort it easier.

Check case capacity. If they're different, then you know the case on the left is most likely mil brass. IMO, though, the case on the left is mil spec.

I recently bought a box of 100ea. Federal rounds at Wallyworld. The box contains rounds of both cases shown. Printing is larger on the cases with 3 dots. Could be they are just manufactured on two different machines.

The three dots indicate it is manufactured on a SCAMP machine which is the latest technology in use at Lake City.  Should be mil-spec.

OP, I agree with earlier post - large letter on right is likely not great but small letter on left IS mil-spec.
