Quoted: Awesome thanks very much. Now I just have to find a 5.56mm rifle I like that doesn't cost as much as an AR Mini-14, FTW!!  ETA: Incidentally, this is the reason Minis ruled the roost back in the '80s: ARs were relatively more expensive and not as readily available as the Minis were. |

You can pick up an AR for pretty cheap still, definitely sub $800 (at least in some local shops here)
I'd go with a Mini if you can't get an AR. They're OK. |

Oh God, here we go... "The .223 Remington is rated for a maximum of 50,000 CUP while the 5.56mm is rated for 60,000 CUP. That extra 10,000 CUP is likely sufficient to cause a failure in a chamber that's only rated for the "sporting" .223 Remington. The .223 Remington and the 5.56mm NATO, when checked with a chamber ream from a reliable manufacturer of each, also have discernable differences in the areas of freebore diameter, freebore length (leade) and angle of the throat." |

Basically, yes.
While there are a few dimensional differences between the two rounds, the main difference is the chamber pressure... Think of 5.56 as .223 Magnum... Or .223 as 5.56 Special... Either way, 5.56 is hotter and higher in chamber pressure, even if they look almost identical. However, many guns that are marked ".223" are actually chambered in 5.56, which makes it all the more confusing... A good general rule of thumb is, if it's an old bolt gun that says ".223", don't dare shoot 5.56 in it. |

I don't yet own an ar or any rifle in this cartridge. I was told by my friend if I want to be able to shoot military 5.56 I need a 5.56 rifle. (this makes since as I'd only want to shoot what it is chambered for). Is it true 5.56 can shoot both and .223 can only shoot .223? Very few rifles have a tight .223 chamber. Most rifles will handle both 5.56 and .223. (Wylde chamber) The most common exception is match rifles. The tighter leade and throat of a match rifle makes shooting 5.56 dangerous at worst (I have yet to hear about a KB from running 5.56 in a .223 ) and will cause cycling problems at best if it is an AR platform.

I have understood it is best not to put 5.56 in a .223 gun. I thought it was something to do with the throat of the chamber being a millimeter different.
Now I look and see several people do it and think nothing of it. So, what about putting 5.56 ammo in a Remington 700 .223 ? Thanks, Ed |
