I recently purchased my first "black" rifle as was mention in another thread. I do most of my own reloading but have never loaded for 223. I was concerned that there might be differences between the 5.56 and the 223 but found out that you can load to 223 specs and be ok for AR's chambered for 5.56/223. I've checked on this via google search but wanted to double check with some pro's that we have here in this forum. I've got 1500 rounds of lake city brass coming (once fired and cleaned) to my house and ordered the 223 dies this morning. I just want to make sure that I'm good loading this brass to 223 specs.
