Does steel case ammo hurt AR's?????

[Dan-o]

Hi,

I'm fairly new to AR's, but between my kids and I we now have 5.......   Tons of fun burning up ammo.

QUESTION:    I see all of this cheap steel cased ammo and I wonder if it's bad for ARs.   Do the steel case trash the bore/throat?   Is there a reason not to buy it for cheap plinking ammo?

Thanks,

Dan

If you're going to do cheap plinking in one dedicated gun I think you'll be fine. I wouldn't do it through your home defense / zombie apocalypse gun. If you shoot a lot, you'll likely save enough money that it will be worth whatever maleffects the steel brings. I'd have no problem running the polymer coated steel rounds through an AK as they were designed for that kind of dogpoo. I wouldn't run it through an AR, especially a nice one, myself. You'll get more buildup in the chamber and some occasional failure to extract problems. IIRC its because the steel doesn't form as good of a seal in the chamber as does a brass case, and with some of the resultant blowback robs the BCG of enough energy to properly extract.  Clean it good especially if you're going to shoot brass in the same gun later.

Thanks, Bean!

There is a rather long article somewhere on the internets where steel ammo was compared to Federal (If I remember correctly).  The Steel bullet wore at a much higher rate and the barrel with the Federal ammo stayed accurate much longer.

Gun problems often come back to a couple of things, bad ammo or bad mags.  Don't go cheap with either.

If that's the same article I remember it also showed that in the long run it was cheaper to shoot the cheap steel cased ammo and replace the barrel a couple times.

Me personally I have one ar and shoot whatever I have through it. It's nothing fancy and barrels are cheap.   

Now if I had a match gun or something I plan for extreme accuracy I would think differently

I've shot both through my AR10. I won't be shooting a lot of steel ammo but I have some stockpiled if the need arises for it. It's good to have this information, though. Unfortunately, good ammo for my rifle is $1+ per shot (6.5 Grendel). I also thoroughly clean the bolt carrier group, action, and barrel when I get done each time I shoot it, steel or otherwise. So far, I've noticed no buildup at all.

The article was a endurance test on ammo. 4 new DPMS rifles were purchased 20k rnds to be run through  each. 2 brands of brass 2 of steel. At 7k one of the steel case guns had a catastrophic failure so it couldn't finish the test. The other steel case wore out the barrel  in less than 10k rnds. I think they were cleaned and made some measurements to determine wear.
Imo an AK is the only weapon I'd run steel through. They don't seem to care.

my experience is that a considerable lacquer build-up was found from use of steel cases, eventually leading to restricted feed problems and incomplete bolt closure issues.

This is the EXACT reason I sold my Grendel AR and built a bolt action Grendel instead.  Way too expensive to just blow through ammo at more than $1 per round.
I've used steel ammo in AR's before with no problems though.  However if looking for accuracy you won't find anything mind blowing in steel cased ammo probably.  Just as plinking ammo I wouldn't hesitate to use it again though.

I had a thought.  How about a dedicated barrel to shoot steel when just having fun with it.

I've been thinking about that.

I do love to make noise with the thing, and a dedicated barrel might make a ton of sense for just screwing around.

Brass is significantly better, though it's probably a wash on price between the two. The brass will take longer to burn out your barrel, but for what you save on ammo, you could buy a new barrel.

The new zinc  coated steel would work much better that that azure stuff. The laqure will turn your AR into a jam o matic as soon as it get hot.

I've heard good things about the zinc covered steel and I wonder how the zinc would affect long-term wear, does it provide extra lubricity, to negate the hardness of the steel.

I am thinking that bullet jacket material has more affect on barrel life and wear than the cartridge case. Lots of the steel faded ammo uses bullet jackets with steel in them.

I still really don't care what I feed my ar... as long as it shoots. I also don't shoot it a ton. Maybe 1-2 times a year.
