God, I hope this isnt like 'Tires and Oil', on another popular Forum.
I have been shooting Remington UMC .223 55gr out of an Olympic Arms AR-15.
I bought the ammo at Walmart.
I've been getting alot of extraction jam's. Casing's not coming out of the breach.
Stove piped 3.
I've cleaned and lubed everyting. I even replaced the o-ring on the extracter.
It still does not eject the spent shell case, all the time.(tight breach)?
I went thru a 30 round mag and half of another and then it failed to eject the spent case.
The barrell was too hot to keep my fingers on it.
Today I bought 'Federal 'Power Shock' 223 55 gr. soft points.
They shot flawless.(but cost twice as much) Then I loaded the Remington's. Back to the extraction problem.
Anyone else have a rifle that is 'sensitive' to ammo? Thoughts, ideas?

I know my 870 didn't like cheap ammo initially, and I know my .22 doesn't either.

You gotta find what works in your gun and shoot it.

My Walther P22 is a little picky, but has become less picky over time.
At first, it was high velocity rounds only. Now it can feed standard velocity rounds as well at about 95% reliability. Sub-sonic, you can forget it.

Considering that Walther puts the break-in for the pistol at 500 rounds, the ammo situation was not unexpected.

P.S., Remington Golden bullets don't work very well in my friend's Ruger 10/22, but just about everything else does.

Put a few hundred rounds more through it. It the problem still persists, contact Oly Arms.

James

Got ya! Are you thinking 'tight breach'?
Barrel is marked 556.
I'm gonna try to run out the Remington I have left.
I have a bag of .223 and .40 S&W brass for ya.

The one thing Oly usually does right is their barrels so I'm not sure the breach is tight. Extractor tension may be an issue. Make sure you have the right colored spring for your extractor. BCM makes a good kit for carbines. What barrel / gas system configuration are you running?

James

The extractor spring is silver/grey in color. I'm unsure how to describe the the
barrel / gas system except to say, 'its the original/traditional gas style'.
Thanks for the link!

I have on the way: 741-015-003 AR15/M16 D-FENDER D-RING <<< Got this idea from AR-15 magazine.
100-004-041 AR-15 HEAVY DUTY EXTRACTOR SPRING
From Brownells

I could be that the cheap ammo is loaded lower so that it does not have enough oompf to send the bolt back all the way for a clean ejection.
Just a thought

Another good reason to roll your own

James

Picked up a box of 20 "American Eagle, Tactical XM193, 5.56 x45mm, 55 gr FMJ".
Gonna give these a try.
Thanks for the suggestions!
Jim

Metonymy

American Eagle isn't the same as XM193. Although Federal makes both of them, the American Eagle is a pure .223 round, and the XM193 is a 5.56 round.

Both should cycle in your rifle just fine.

Oh... be aware... the XM193 rounds... they're going to stink. It's the powder they use.

James

Sorry, but is printed on the side of the box 'American Eagle Tactical XM193'.
They are 5.56 X 45MM

FatFugg

Yup! I got some right here.

Metonymy

Ohhhh.... You're talking about the black box with white writing. I'm thinking of the red/yellow box. (added pics below for reference)

From what I've read, it's really .223 ammo loaded into the lake city brass. Either way, they'll cycle your rifle, and they're going to smell strange. :)

James

Yup! The Black and White box! I bought 20 rounds, 'to try it out'.

James

I recieved the 'D' O-ring and H.D. extracter spring today!

Brianaintright

I was asking if your gas system is carbine length, mid length or rifle length and what length the barrel is. Sometimes the wrong parts combination can cause issues and it helps determine what extractor spring needs to be used. Usually, the extractor spring color is determined by the insert in the middle of it.

I apologize for not being more specific.

migxdm

might be a bad batch, meet with me and I can measure them for you. or you can clal the company and tell them and they will replace them (from personal experience)

James

I apologize for my ignorance. I don't know. Its a Carbine, by Olympic Arms.
How do I measure the length of the rifles system?

James

I cant. I'm in SE Wa.

GregM

On my FAL there is an adjustment that you do to divert more or less gas back to the ejection mechanism. You adjust it until the ejector operates properly after a round is fired.

James

I did a combination of things.
It had an A-2 handle/upper receiver on the rifle.
Its now a flat-top rail receiver.
I also replaced the extracter spring with a Brownell' HD replacement spring.
I add a 'D' o'ring to replace the stock o'ring.
Took it to the range and ran (2) 30 round mags of the Remington .223 rounds.
(The stuff that was not ejecting)
It's working like its supposed too! Not a hick-up!
Many Thanks to all for ALL your help!

No sweat James. Sometimes it's difficult for gun geeks to remember back when they were just starting out. My fault not yours. I don't think Oly makes a mid length so if it's not a full size rifle with a 20" barrel, you have a carbine length gas system. It's the shortest of the common three types.

GixxerPete

The only ammo that's ever jammed in my AR are your reloads.

migxdm

thats cuz it was my first learner batch butt puncher!

migxdm

mail me a few

JayD1981

I know how you feel. I started reloading about 6 months ago. I had a 200 round batch of 9mm that my carry pistol hated. I guess the starting charge wasn't enough to get it to chamber the next round. Luckily my Mac10 didn't mind it so I still was able to use them.

James

Can't! Got the gun working. Shot'em ALL up!
All's I got left is the brass and, I gave that to JD1981!
But, Thanks for the offer!

James

My local Tru-Value Hardware store has on Sale "Federal XM193 Rounds"
55gr 900rd Case Stripper Clip 5.56mm Ammo
Metal case, boat tail, ball.
$348.00+ tax case of 900

Is this a good price?
