Question, since I don't know much about 556 ammo, is there a good reason for me to keep this order for the XM193 NATO stuff, which is about $45 more than I could get a case of AE223M? I have no idea what the difference is between them, from a pure target practice perspective. I'm kicking myself for not looking into pricing before jumping on the deal. Seems prices for 223/556 is cheaper than the last time I bought by quite a bit.
Bring deeply ingrained into AR's I have both target and car disabling ammo. But that is just me. If you are not looking at tis rifle as a HD/retaliation platform then just lean towards target ammo.
I have my mags loaded and labeled as to intent and separated into ammo containers. But that is just me. Stay away from the "El-Cheapo" crap ammo. It runs dirty and is not near as much fun to run.
