I don't own a rifle that fires these calibers but I know the general difference between the two. I happen to commonly collect tons of these brass from the range. And so for all you rifle owners who reloads these calibers, would you want a brass seller like me to separate the 223 vs 5.56 to sell them separately? Or does it not matter? If so, would you also prefer that the 5.56 be separated from the 5.56 NATO to buy each type separately or does that not matter? Thanks in advance for all your answers.
