 Federal XM193 vs. American Eagle (Federal) .223

Sorry if this topic has been covered before, as you might guess I don’t hang out in the Ammo Forum very often.

My ammo purchasing habits consist buying a 100rds or so every payday and storing up through the winter for my warmer weather shooting. So my ammo collection consists of a mix match of different brands, some WWB from WalMart, some of the Green boxed Remington .223 from WalMart, XM193 and Federal American Eagle .223. And of course a few boxes of Wolf.

I picked up this American Eagle .223 today and noticed that the headstamp is the same as the XM193 I purchased. Both are stamped LC which, correct me if I’m wrong, stands for Lake City? But the real question is, “Are both these rounds identical as far as performance?” The headstamps look identical with the exception of the mfgr date.

Again, sorry if this is a dupe, ammo is unfortunately my weak area when it comes to AR’s.

That's a great price on the XM193.

Yea, that's what I thought too. I purchased it about a year ago, unfortunately where I bought it dosen't carry it anymore (Gander Mtn).

I haven't seen that headstamp on the FAE before. My understanding, and I may be wrong, was that the NATO cross signified a military specification loaded round. It appears that you got a better quality brass than usual with FAE at the very least. Wonder how hot it is loaded?

The AE works really good for me I think it is rated around 3240 FPS I am not sure about XM193. The stampings on my AE looks like yours, although I have another case that is stamped FC.

Both are good!

also the Federal A.E. did pretty well considering its a FMJ loaded to 223 pressures

check out the Gel test at federals web site

I thought they both had GOLD color PRIMMERS?

These are not the same. The xm193 is basically a copy of the M193. The commercial Federal AE with the same NATO stamped cases are the same cases, and possibly the same heads, but not the same powder charge.

Word around the campfire is that Federal has been making LC cases in their commercial plants to help with the LC contract. Some of these have been used in the commercial Federal AE. These cases are thicker (and better) than the usual 223 AE cases.

So the question for the reloader is: Are these cases EXACTLY the same as the typical LC we've been using? I buy/pick up as much LC brass as I can come by. Knowing this, it would make it a lot easier for me to purchase AE ammo for plinking/storage, IF the brass is true LC spec.

Hey thanks a lot! Got the page and downloaded the .pdf's!

Doesn't look like much of a difference.

For all to enjoy!

Looks like the AE223 has higher velocity and muzzle energy.

I'm not a ballistician, but I'd figure on a good bit of the vel and subsequent energy difference to come from the different test barrels. "5.56 test barrel" vs a 24" SAAMI test barrel. I know my 14.5" is around 9.5" shorter than that AE223 test barrel ;)

eta - XM193 vel data taken at 78' from muzzle also... (reading is fundamental)

Good point I didn't catch that. But overall the AE223 doesn’t seem to be bad ammo. I'm gonna buy some more.

XM193 IS M193. it is not a "copy"

Federal does not make brass for Lake City.
Federal buys brass from Lake City.

You will find Lake City brass in almost all of Federal's .223 loads. Not all of the time, but Federal is using it in many loads.

Federal does not make XM193. Lake City does.
(Federal has a product support group, Lake City does not. That is why there is a Federal logo on the box. It gives you someone to call if you experience a problem)

Certainly! We shoot a lot of it here, and I'm going to be buying a large mess of the stuff for this summer. I was being sarcastic at myself for missing the measure point :) I haven't seen any issues with the AE223.

That info was one of the reasons I changed to AE for range ammo some time ago. Pressure and velocity are almost the same. Don't know about the bullet structure or if it fragments but for the range who cares.

That is the maximum SAAMI pressure. Neither round is run that high in practice.

I have about 400 rounds of 1000 left of the FAE 223. Mine is FC brass, not LC. It is very good ammo. I don't have a crono but I can't tell any difference recoil or noise wise. It is slightly more accuate out of two of my AR'S than the xm193. I've never had a malfunction with the FAE. Don't remember the date on the headstamp. The only reason I would shoot this instead of putting it up, is because of the sealant, or lack of, at the case mouth. Good practice ammo, and I got it cheap.

Remember that the .223 load is generally loaded on thinner brass and fired in a tighter chamber than the 5.56 load. Just because the PSI readings are nearly identical dosen't mean the ammo is.
