    Question Do you run steel cased?

    Through your AR?
    Or do you not concern yourself. I keep hearing not to run steel cased 556/223 through my 6920.

    I have run some through mine, haven't noticed any problems with running it through there. I prefer to run brass cased, but sometimes the economy dictates steel cased.

    I cannot reliably fire steel cased ammo in my LMT rifle while my other buddies have no issues in other rifles. My extractor tends to chew into those steel cases quite a bit, but has never had issue with brass.

    The main issue as I see it is that typically the steel cased ammunition is of cheaper grade and as such you have to be mindful if you are buying corrosive vs. non-corrosive ammunition.

    Yes, I run steel cased ammo, specifically Wolf and it runs just fine. If I shoot a lot, after a while I may get a FTE. I clear the jam, run a chamber brush several times, and I'm good to go. I primarily use brass cased ammo, but for general plinking or in areas where I can't scavange my brass (or anyone else's!) I'll shoot the steel cased ammo.

    Here, go there... or otha' thready's...

    I think proper extraction depends on many variables..I.E. Friction coefficient of the case material, Annealing between case and chamber, extractor material and spring tension...Blah blah blah...

    Some AR-15 manufacturers will not warrantee their guns if you run steel cased ammo through them. It's a simple matter of physics -- gun chambers are made of steel, which is harder than brass. When running brass cases, the brass wears from the friction between the case and the chamber, not the chamber. When running steel cases, steel-on-steel causes both to wear.

    So, you can buy cheap steel cased ammo all you want, but you're wearing out your gun chamber every time you squeeze the trigger. And like I said, some of the manufacturers won't warrantee the gun when you develop problems from this. Save money on ammo, buy a whole new gun! That doesn't seem worth it to me.

    One of the biggest issues is chamber size. A 5.56 chamber is a little looser than .223.

    New production stuff shouldn't be corrosive. There is, however, a butt-load of older ammo out there that still is. Or that lacquer-coated Bear crap...

    That, plus old steel casings expanding in a steel chamber makes it lock the phuck up!!!

    And they'll know if you do it, too.

    Steel casings in steel chambers requires lots of lube. Almost sloppy wet - like you want your girl to be. Fekkin' lube everywhere.... If it eeks out the back of the bolt carrier and through the area where the charging handle latches...well, that's too much. But you get the idea. Lots of lube and clean it like a transient in intake - scrub the SHEOT out of it.

    Hummmmm... well 5.56 mm = 0.233 inches I 'dink..... Sooooo, yaz a say'in dat da' loaded non-fired cartridge 5.56mm x45mm is smaller dan' da' chamber for "fire form'in" (kinda' like annealing) like I did's declares in above testimony...


    New production stuff shouldn't be corrosive. There is, however, a butt-load of older ammo out there that still is. Or that lacquer-coated Bear crap...
    Well if da' primers are "hard" or as ya'll say coRrosive like, just throw it in a gay bath house...... (afta' yaz' shoot da' holy hell outta' it)....... wid' lots O' steam and other stuff, then scrub a' dub away's ......until all da' rust is off da' lands and lays inside da' BBL. Den' ya gots a nice new "slick" tube..

    BTW Sarge.... I never did see dis' here stuffy called "lacquer-coated Bear crap....not dat' iz' a say'in dar' not such a critter...I just nevea' seen bear crap on a loaded cartridge befer'....


    That, plus old steel casings expanding in a steel chamber makes it lock the phuck up!!!


    And they'll know if you do it, too.
    who's they??? I ask thee??

    But if yaz' grease it up all up real good, like Ma' girl Mary Lu, won't dat' cause much higher chamber pressures due ta' da' lack of da' case, again, fireform'in ta' da' inside Of da' chamber????? because da' expand'in cartidge has noth'in ta' grab onta', like da' chamber, ta' fire form ta'???












    Or is da' ammo such crap that it's got a bad case of da' pimples......


    Now's, in my next threadY thingy, Iz a' gunna' go through da' whole "process" from pull'in da' charg'in handle back ta' da' bullet leav'in da' muzzle....And I mean everthaNg, I is...
