Is it ok to shoot Silver Bear .223/5.56 out of my M4gerys? I have only shot brass cased in the past but the price on spam cans of Silver Bear is pretty attractive. GB and SB are good quality ammo for the AK's but what are your thoughts for use on the AR's? Will it chew up my feed ramps and wear out the internals prematurely? Any input would be appreciated. Thanks in advance.
Silver Bear .223
Steel cases, steel core's corrosive powder. It will wear on your gun, the extractor will be the first sign of trouble.
You will get plenty of people that will tell you its fine, they shoot it out of their AR all the time, and I'll respond a head of time by saying that it hasnt caught up to them yet. In a pinch, I suppose its better than nothing, but I wouldnt risk my rifle or create more work in cleaning and maintaining in order to save a few bucks.

I've shot about 700 rds of Wolf and Brown Bear out of my ARs without any problems, some people say it is to much wear on extractor but I haven't had any failures or know anyone who has. There was a problem with the older Wolf because of the lacquer coating but it has been corrected. I also use the Wolf and Silver Bear 9x18mm Mak out of my CZ 82, FEG PA 63, and P 64 for target practice.
Got this from another forum.

"This is a myth. The steel alloys used in these cases are as soft as the brass they replace.
The steel is soft, but not quite as soft as brass. That being said, it's still sufficiently soft so that it shouldn't be doing a number on your extractor, and I just ordered 500 rounds to put through my AR.
Supporting data (my own hardness tests, each case once fired):
Wolf Steel Case - 96.2 HRB
Winchester Brass Case - 80.0HRB"

My Bushmaster manual says Wolf ammo is okay to shoot, but I personally steer clear on the steel case ammo.
I'm sure a limited amount may be okay but that's just opinion on my part.
If I was going to fire any laquer coated ammo out of my AR I would shoot it after firing any brass ammo I was going to shoot that day.
In short, make it the last ammo you shoot before cleaning.
Just my $0.02.
Generally, I don't like shooting the steel case ammo when other alternatives are available. With that said, I bought 1000 rounds of the Golden Bear .223 62gr. JHP ammo. Fired about 20 rounds just to make sure it functioned. The remainder is in a GI ammo can, sitting on a shelf in my gun room waiting for a SHTF scenario. If things were to get bad, I don't care if it's steel, brass or plastic -- as long as it works, goes bang and I have it.

Ammunition manufactured by the JSC Barnaul Machine Tool Plant is likely the best of the Russian offerings. They manufacture the three "Bears" and other brand names on a contractual basis.
Do the math on how much more shooting you can do for the same amount of money. If you're worried about a broken extractor, buy a couple of spares.

Its a non issue. Extractors are wear-items in the first place. Keep a few on hand, clean your chamber good and stop caring. Even if its corrosive, so what. Clean your equipment and check all wear-items.
While this is a valid point, it only rings true with a range gun. I don't want to replace an extractor in the middle a fight, nor do I want to clean my gas system during a extended situation.
Sure, its a long shot that most of us will ever experience the extremes, but if we subscribed to that logic, why do we have battle rifles and just what are we practicing for?

Why leave something that you're not COMPLETELY sure of for when you need it most? That's like choosing to go out in a snowstorm in a mid-80's Ford Escort when you have a garage stored, well maintained and regularly tested Snowcat sitting just inside the garage. Why risk it?

With all due respect, there is no real evidence of accelerated wear from the steel cased stuff. If you have a good AR (read inference as high quality) it makes no difference. I run Wolf all the time in my BCM and Stag uppers and there is zero wear evident on any parts. My primary carbine (BCM) runs a Daniel Defense BCG, which is top tier and the Stag runs a standard (CMT) BCG, which is milspec.
My opinion is the alleged wear from steel cased ammo is internet rumor. Nothing more.
