| Sorry if this topic has came up already but can't find anything on here or google. Why would someone choose a 5.56 round over .223 and vice versa. I know that the 5.56 is higher pressure but just want to know why some of you choose one over the other. |
|
All of my uppers are 5.56 1/7. For some reason that's just the way it's worked out over the years and I'm glad that it did.
I can shoot 5.56 or .223 consistently without having to worry about overpressure issues. If I were to buy another barrel, upper, or complete rifle I would choose a 5.56 over a .223. |

Well I understand that part. Just wondering about the actual ammo choice. |

The only .223 I have is .55gr Federal TRU. The rest is all M855/M193.
My rifles are more consistent with the heavier M855 and standard M193, and I only keep a couple of mags loaded with the TRU for HD. I'm fairly accurate out to 300 - 400m with the ACOG and the milspec ammo, and if I have to reach out further than that I switch to my .308 bolt gun. |

If I'm going for varmints, I'm using a .223 varmint load that is more accurate out of my rifle than a 5.56. Need to know more information about your intended purpose to help answer your original question. |

This comes from the "ammo oracle" . It can be found by clicking on "tools" located just to the right of your username. It is packed with GREAT info, most definetly worth a look,
http://www.ar15.com/ammo/project/hist_chamber.html Also check out the FAQ's in the ammunition section of AR-15, another wealth of info. http://www.ar15.com/forums/t_3_16/503947_AR15_Ammo_Forum_FAQ.html Edit to add link ( sorry, don't know how to make them "hot") |

I have either NATO or Wylde chambers, so I don't worry about it.
Bulk: I buy good bulk regardless if it is 5.56 or .223. Match: I like good .223. There seem to more quality match ammo in .223. Hunting: I also prefer .223 for the same reason as match. Just better choices. HD: It doesn't matter too much, but I tend to like the 5.56 loads: MK262, MK318, Hornady T2 TAP 77gr. I reload .223 only. I don't want to mess with crimping bullet too much and I will not crimp primers. |
