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.
