    What's the poop on aluminum cases?

    I'm shooting a 1911 5" SA Loaded and have used nothing but brass. I notice CCI makes aluminum-cased 230gr FMJ for a good price.

    Anyone have any experience with these?

    Thanks-

    I've shot some, and it was fine in my 1911 and HK. Had a Glock 21 that absolutely hated the stuff and wouldn't reliably feed or extract it.

    I'd try a box first in the intended platform before ordering any quantity.

    The aluminum cased ammo is great and cheap ammo. However the cases are berdan primed and not reloadable, which in my opinion makes them a bit expensive. If you do not reload, they will make a good practice ammo.
    A hand gun is like a fire extinguisher , I wish to use neither, but have both on hand in case of need ; both are personal protection devices that serve the same purpose . ie safety of you and your family.

    Regardless of the primer, aluminium cases are one-shot items (pardon the pun).

    My Steyr M9-A1, which normally eats anything I give it, choked on some Blazer aluminum. Check it before you buy much of it.

    I save and reload brass. Never bothered with the alum stuff.

    If you are having feed issues then be aware of the fact that Aluminum bearing against Aluminum and Aluminum against the mag feed lips does have some friction drag to it especially under the extreme upward spring pressure of a full magazine.

    By far the easiest feeding cartridges are bright Nickle plated due to the natural lubricity and hardness of Nickle.

    Just a FYI for anybody interested.

    I usually buy bulk aluminum ammo every time I buy a new gun. I have never had any issues with feeding or ejecting.

    I actually reloaded some aluminum cases once just to see if you could,It was only like 2 or 3 cases and they were not berdan primed.They shot without a hitch,but aluminum isn't as resilient as brass and after a couple reloads would probably develop a crack,would I reload a case more than once,probably not unless it was TEOTWAWKI and it was all I had

    as QKshooter said. Aluminum is bad about galling. Brass and aluminum have a huge difference in coefficient of friction. This causes the aluminum to maybe not feed as well in some guns. Ive never thought the price was that much better to go with aluminum. I remember shooting some a long time ago. I dont remember any problems.
    Be careful what you wish for. You just might get it ......

    The "stickiness" of aluminum-cased ammo is frequently more of a problem on extraction after the case has expanded on firing.

    Most of my handguns work OK with Blazer, but a couple choked irregularly. Seems to be an individual gun's preference.

    FWIW.... Expansion rates are different with Alum compared to Brass and shouldn't be used in unsupported chambers. It also tends to be harder on parts such as extractors and ejectors.

    Get a box to test fire before you stock up since aluminum cased ammo (blazer) will jam a lot of guns that are otherwise reliable.

    They have worked well for me in revolver or pistol.
    Do not let them get exposed to salt water or chemicals too much-----it can cause the case to split when fired, so said CCI when I got some split cases from ammo I could only guess it's history
