I just received an order of range brass for .223. After cleaning them, I started separating .223 from the 5.56 brass. During the process my wife asked why I was doing this. Because I had to come up with a good answer I just made up some answer that would allow me to appear knowledgeable in her eyes. Should I separate the .223 from the 5.56 brass? Is there an advantage or disadvantage in this? Does it matter? Wanna kill these ads? We can help!
