AR's wont shoot Steel Case Ammo. ????ss

[fmunk]

I have a few questions for you experienced AR owners. First off, I know I should be feeding them brass cased ammo etc, but it was all that was available at the time.

Internet myth. Bogus. Plenty of bigots will disagree, but I don't really care.

They did the exact same thing, first round shot but did not eject. And it did not look like a FTE, the chamber didnt even attempt to open. Almost like a single shot. We had to manually eject each time.

What exactly do you mean by chamber didn't attempt to open? If it failed to eject, that means the load was too weak to cycle the bolt. Failure to cycle = failure to eject.

I was thinking, either the ammo was soo cheap it didnt have enough power to eject itself? Or perhaps the chambers are so tight that the steel casing just stuck in chamber?

Did you have to use a cleaning rod and tap hammer to forcefully extract the casing? If so yes, the chamber is a little tight. You can reliably shoot steel of you hone the chamber slightly. Do a search on the web, lots of info on this.

On a second note, My PWS Diablo AR pistol shot that same ammo perfect, as well as my brand new DD 12.5 Pistol.
Only the 16" ARs would not cycle the steel case ammo.

The same ammo may just have enough power to cycle the piston. Remember the piston creates a solid connection (read non-compressible, or less compressible) between the gas block and your bolt. In a DI gun the gases in the gas tube between the block and your bolt is your linkage; NOT a solid linkage. Gas is compressible and loses velocity with distance.

This is why piston guns are more reliable in some situations than DI.

Another question is, what is reaming the chamber? Is that were they use a tool to basically scrape out the chamber to make it "looser". Would that allow me to shoot steel case ammo?

Correct term is honing, but yes. You are increasing the interior volume or diameter of the chamber ever so slightly. Done properly will not affect accuracy. It will also increase overall reliability to feed any ammo in adverse conditions; dust, mud, extreme heat/cold etc.

I know if I shoot decent ammo the AR's will shoot excellent as they did, However it would be nice to know they CAN shoot any and all ammo.
I really dont think they need to be broken In, because they shot the brass case ammo.

That is true of ANY ammo, brass or steel. Not all steel ammo are equal. If you are going to buy steel ammo, get decent stuff. WPA, Wolf Military Classic, Golden Bear, Brown Bear, etc.

Again, tons of info on the web. Search!

Interesting I'd always heard it was slower but your explanation makes sense especially about the straighter body.

People just don't understand that brass cases are part of the overall design of US auto loading rifles.
The 7.62x51 has similar case body taper to the 5.56x45 and also relies on the expansion/contraction properties of a brass case.

The ability of an AR to run steel cased ammo mostly has to do with a loose chamber/throat and a smooth polished chamber to ease extraction.

The loose throat/chamber keeps pressure down so that the steel does not expand as much.

The smooth chamber walls help keep the cases from sticking.

I would not fault an AR that won't run steel case ammo because it was not DESIGNED to run steel case ammo.

And it doesn't take much to get one that wouldn't run to run. The issue of ARs and steel ammo is overhyped and blown out of proportion.

My 2 del-tons are fine with most russian ammo. I stay away from wolf because it seems to be the most underpowered. I have a bunch of herter's and tula and I have no issues with that ammo.

Wolf and Tula come out of the same plant.

Just because they do doesn't mean they are the same grade. Even among the Wolf brand offerings there are different grades.

What delton rifle do you have i have the optics ready and i have the same issue. when i use .223 tulammo i have problems with that ammo tried different mags,steel,pmags but when i run my 5.56 federal or .223 remington the rifle shoots like a champ.

It's the same stuff but if it makes someone happier to buy Tula brand vs. Wolf brand steel case ammo by all means go for it.

I have a mid length and a M4. Both are flat tops and chrome lined. Almost all my ammo stash is herters and tula. The ammo is somewhat underpowered but it runs.

As for tula and wolf being the same I wouldn't agree. I had a batch of wolf a while back that gave my guns problems. I would get stuck shells and it seemed that steel was more brittle on the cases. My extractor would rip off part of the rim of the case. The case would still be in the chamber but even the rim was ripped off the cases came out fairly easy with a rod down the barrel. This happened alot. I could take the same gun and immediately run tula and it was fine.
