.223 V 5.56 why everything you know might be wrong.

Interesting and informative article I read.

Another reason to load your own.

All my rifles are chambered for the 5.56 and I don't buy cheep ammo.

I've nothing against reloading and still hope to get into someday but I don't think there is a problem with factory ammo as long as you don't try to cut corners and buy cheep.

Just my opinion of course.

I want my rifle to be Minute-Of-Man. If I can hit a man sized target with it at a reasonable distance, I call that good. I've yet to run across ammo that could not produce that, and I love me some cheap dirty Russky ammo.

If I were concerned about super-accuracy then I'd start to care about chamber this or ammo pressure that.

_{This question has been bothering me since my wife bought me 5.56 for my .223 rifle. For every search I have done I seem to get different answers. If I understand this article correctly he seems to think no harm would be done on firing 5.56 in a .223 weapon every once in a wial. Even still I am not going to risk it.}

_{With this being said anyone want to trade 100 rounds of American Eagle for 80 rounds of .223?}

That's about all I'm good for, nowadays. Minute-of Man. I like that, Spock.

I've always heard you're not supposed to use 5.56 in a .223, because it can blow up your gun. However, I have never seen a case that I van recall of it every happening. It may well be a case of much ado about nothing.

i shot 5.56 in a 223 chamber many times. nothing happen.

I find it interesting that he was in some cases recording higher pressures in a rifle chambered for 5.56 than in one chambered for .223.

I have one AR that's chambered in .223. I have done the chamber measurements on it. No way I can jam an 80 grain Berger into the lands. I run out of bullet first. I think some manufacturers probably lengthen the .223 chamber spec just to minimize the pressure Spike. I can shoot 5.56 in that gun with no problems.

A Hornady OAL Gauge will tell you for sure.

When I was a youngster, I went scuba diving in a cave, alone, and without ever having had any cave diving training.

The fact that I lived through the experience does not mean it was a wise decision.
