I was wondering why some AR's will shoot it and some don't?  I have a DPMS Recon and the rifle just wont shoot it at all.  I have tried all the brands and only Herters will work sometimes and even then every 5 rounds it wont cycle the rifle.  Would love some answers.

It's often under powered, therefore causes cycling issues in some rifles.
Lightening your buffer will usually help, but seeings as you have a DPMS, I'm sure it came with a carbine buffer which is already the lightest buffer I know of.


That said, all my AR's shoot steel fine - even with H and H2 buffers...

If you are properly lubing the gun there shouldn't be any problems. What problems are you having?

Has nothing to do with lube. Steel ammo being under powered causes cycling issues in some guns. Plain and simple.

Not getting into a pissing match with ya.

The OP asked a question and didn't elaborate on the particular issue with the ammo/gun.  I've never had ANY steel cased ammo not cycle a gun, thus my question. You can take it from here...

Lube or even over-lubrication is not always the answer. Most steel cased ammo is the cheap stuff like Tula or Wolf (for what I found Wolf is far better). But what they seem to do is use a fast burning cheap powder. The powder burn rate is different enough to be not correct for the operation system in your rifle.

Think of the burn rate as a power curve. Sometimes it peaks before it has enough residue energy to power the complete operation. Not enough gas left to put enough energy in the gas tube.  Best fix; try to lighten the buffer (even take out a weight... that is drastic).

I have a AR pistol it likes to rip of the rim off (extraction groove) where it is engaged by the extractor. Since the peak pressure peaks at the gas port. (but it shoots well except for that pesky extraction thing).

The hard part for a semi-auto rifle operation is to have ammo that gets the powder charge right. Tula

The problem isn't caused by lack of lube but if you're running low powered ammo and a dry gun then it can help in some cases. Seen it first hand.

My personal experiences:  I shoot BCM's exclusively.  Haven't had any issues with steel cased ammo in them.  

What I have seen:  People with DPMS, Stag, and other non-mil-spec guns usually choke or hard lock with steel cased ammo.  

Also note:  If I'm dumping like 120-150 rounds super fast my BCMs will choke on steel cased.

Not all steel cased is the same.  I run Brown or Silver Bear in all my rifles, and they all shoot it just fine.

Tula/old Wolf - more than half those same rifles would not cycle reliably with it - including my factory Colt R6500, my FNC and my Daewoo DR-200 (last two are piston rifles, btw).

My bcm 14.5 carbine and 11.5 spikes both will run tula or Wolf with out issues 99.9% of the time.  I have had only one round that did not eject fully which gave me a chance to practice a failure.  Cleared jam and emptied the mag.  My bcm has probably 2k  of Wolf out of the 5k through it with zeros malfunctions the Spikes has seen 500 rounds of tula with one

Can you give us more details?

- Does normal ammo run without issue?
- What is the round count of your gun?
- Have you changed any of the factory parts?
- How long has it been since you've properly cleaned your chamber?

My rra entry tac 16" car runs steel fine

BCM  20" rifle won't run steel at all

BCM 14.5 middy runs steel fine

I have no idea why but that's the case.

I don't shot steel case ammo..... period.

Thanks for all the advice so far.  Let me try and give you guys some more info.  All brass case ammo I have tried works great and with no problems at all, and I have put  all  ammo that is available from Cabelas  and Walmart through it and it functions without a hiccup.  I have about a thousand rounds through the rifle and clean it and lube it up after every couple of hundred rounds.  I have added a Raptor charging handle and that's it.   I would like to shoot steel case ammo just because its cheap but its not going to ruin my world if I cant.  Like most you guys I just like to know how my weapon works and if there is any problems that can be solved by getting some advice.  Thanks again.

My Palmetto rifle shoots WPA Military Classic .223 62 GR. with out any problems at all. I haven't tried it yet in my new build though. Of course this is the only steel case ammo I've tried.

Baloney, I've shot mountains of the stuff, it's great for stuff like carbine classes where most of the shooting is relatively short range.

All my 14.5s and 16" will run it and thats Colt,Bushmaster,POSA and Windham barrels....tula will cause short strokes in my 20".

I shoot 90% steel, 10% brass. No problems. If my rifle won't cycle the cheapest, crappiest ammo I got, I get rid of the rifle.

Thanks for the additional details.  I'd still like to know more about what ammo you've used, but I'll make some assumptions for now.

Are you just shooting Herter's and Tula.  I know Tula is weak, not sure about Herter's.  If this is the steel cased ammo you are using, trying something else.

It's not clear what kind of malfunctions you're suffering.  Does the spent case eject but a new one not load?  Does the spent case not extract at all?  Does the round get extracted but not fully ejected?

It sounds like your best solution would be to run hotter ammo (or try a lighter buffer), but if your extractor is mediocre it could be playing a role here as well.

Dpms oracl parts kit on an aero lower, all I've ever put through it is herters(tulammo) with 500rounds so far. It runs flawlessly.

RRA 16" midlength has about 5k rounds fired with about 800-1000 being Tula or wolf it has had zero issues with all types of ammo.

I have owned at least a dozen different uppers and I have never had an issue with steel cased ammo and rarely shoot brass cased ammo.

Gas port size/buffer weight is the two major things that might keep a rifle from running it.

Underpowered, use something that works OR get a reduce power buffer/recoil spring.

I have some steel ammo but dont use it. Got it cheap.

I have used Silver Bear 55gr. HP and it runs just fine in my 18" 1/8 wylde mid length build.

Well to be more specific I was shooting Herters and it would shoot a couple of rounds and not fully eject and the rifle would try and chamber another round.  I have also shot Wolf and Golden bear and had similar results.  So is there a way to tell what weight buffer I have in my rifle or do I have to weigh it?  Also do I have to change a spring along with the buffer?

I have run several hundred rounds of Tula through my S&W with no issues, not one problem.
