Was at the LGS today and they have Federal 5.56 for $8.99/box. WM has American Eagle .223 for $6.99.

I know about the pressure differences between the two and my rifle can handle 5.56.

For shooting at 100yd paper and not much else, is there any other reason to get the Federal 5.56?

I mostly use AE 223 from Walmart. Never have a problem and accuracy is good for punching papers.

The 5.56 should be loaded a little hotter but its not that big of a difference. It would probably help if you are shooting at longer distances.

I shoot both, at those prices, I would buy the .223. I really cant tell much difference when plinking or punching paper.

because 5.56 sounds so much better then 223. Just think about it...

FA-FA-SIX is Kooler then two-two-three.

besides, the military uses it so it must be good! ;)

I can't tell a difference between either, I bought a couple of boxes from my LGS and loaded my mags aternating between two rnds .223 and two rnds 5.56, did another that started .223 and halfway thru changed to 5.56 and when at the range popping rounds, I never felt, heard, or noticed any difference. Almost makes me think that when you buy this commercially available "5.56" it is all just a "packaging" change. I have not tried any IMO "legit" surplus 5.56.

You are going to need a chronograph to see the difference.

Its not just a packaging change.

The price difference could have been from grain too. Not all 5.56 is going to be the same as M855.

Either way, $6.99 plus tax is $.38 per round which is insane to pay, especially for generic .223.

Wow, you just sold me on the 5.56. Was about to pick up a case of .223 but I guess I'm going for the 5.56 now. Haha.

The AK is a far superior weapon then the AR.

M855 feels different than .223

M193 feels the same as .223

Might be just a coincidence, but last time I was out I was hitting M855 5.56 62 grain better than M193 or .223. I have a 1/8 twist and they say 60 grain and up is better for that twist. Though I have friends who say 55 grains shoot great in their 1/8.

For all intents and purposes it's all the same. People shooting AR rifles need to quit worrying about the "differences".

American Eagle 223 is in fact Lake City Arsenal 5.56. The only time there is any concern is with certain 5.56 loads with heavy bullets if shot in ".223" rifles. Do the reading and decide for yourself...........

So $.49 per round for generic 5.56 is even more insane?

What are cheaper alternatives?
Steel?
Online + shipping?
Gun show + parking + entry?

In my opinion, $.49/rd is too much more for normal 5.56.

Steel is definitely cheaper than brass, but you won't be able to recover brass for reload.

Online steel is even cheap, assuming you buy large enough quantity to average out the shipping cost.

Local group buy may be an option too.

Quick and easy comparison: $0.30/rd of 5.56 or .223 is a good price. Lower is better. Higher is less so.

Last case I bought was $286 shipped from Palmetto for 1K rds of Federal M193 (5.56). I've only got 300 or so rounds left, and am not looking forward to trying to find good deals right now. :/

I primarily shoot PMC 233 with some AE M193 thrown in. Accuracy seems about the same but I rarely shoot from a bench rest so thats strictly a seat of pants observation. With my shortened barrel Mini 14 there is a noticeable difference in report between them. At my local indoor range the M193 is an attention getter - noticeable increase of flame and noise. So awesome!
