Brass vs Aluminum case

[Doc Holliday]

Talking about CCI brand here....between their brass and aluminum 9mm, is the only difference the case? Are the bullets, primer and powder the same? If so, seems to me that I may as well carry the aluminum to lighten things up a bit...since I don't reload...

No one here is going to know that for a fact unless they've worked for CCI but an educated guess says that the case is the only difference.

Why? Because I spent some time in Manufacturing Engineering in my younger days and it's cheaper to keep everything the same except for cases, therefore that's the way they would go.

By the way, I've reloaded a couple of boxes of aluminum over the years and they're okay for once or twice.

Only indication I have is running them both through a MAC, and they both produce the same cycle rate.

That indicates to me that they are the same bullet weight, as advertised, and the same, or very similar, components.

I don't know the formula they are currently using.. but in the 80"s when I was in the Mid-east, the Saudis where shooting CCI aluminum case ammo in their Port Said's. I shot a lot of it and it worked just like brass cased ammo.

The case is the only difference. They would not go so far as to make a new powder or primer just for aluminum cases. I know right now for a fact that the US government is getting quotes on making handgun and rifle ammo using plastic cases. I have a small amount of the here with me.

The CCI aluminum cased 9MM was Berdan primed.

Running through a mac? If you want to have oob I heard its not good with open bolt. Any how always had feed issues in a 45 1911

So what... they are not ment to.be reloadable. They were ment to be cheap to make.

Just responding to... That they actually "just" used a different primer...

A friend supplied the ammo that day. Ran through 1K rounds of his aluminum after I had run 3 mags of my brass. No issues with the aluminum at all. Perhaps it's because I run a Lage upper. I haven't run the original MAC upper in several years.

I ran a bunch of aluminum in the Glock and they ran great, never a problem. I would hazard a guess they are the same except for the case.

hey j, here is what cci sent me a few years back about the differences between blazer brass 9mm 115gr fmj and cci blazer aluminum 115gr fmj. i always thought the aluminum was a bit hotter as well when putting it though shorter barrels. :?

i do not work for cci as well just relaying what i was told on their "factory specs" or at least what they are going for.

blazer brass cased 115 grain fmj travels at 1125 feet per sec with 323 ft/lbs of energy. it is boxer primed and fully reloadable.

blazer brass aluminum cased 115 grain fmj travels at 1145 feet per second and brings 341 ft/lbs of energy. it is boxer primed and not recommended for reloading.

hope this answers your question. coolio....

if this is not what you are going for..... i will go out back and chrono both of them for you at the muzzle and lets say 25 yards out too. pick a barrel length or gun and i'll get er' done!! :dance: :dance:

Interesting, thanks for the info!
