i have just aquired a jr 9mm carbine and was wondering has anyone out there ever put any aluminum cased ammo (blazer) through this rifle....if so how many roulds and how did it go
i've heard blazer isn't recommended for blow back carbines but a friend of mine says he hasn't had any problems with it

i just want to get some more opinions
thanks

I used it in a High Point 9mm carbine with no ill effects. I had only about 1000 rounds through it when I sold it off, but most of that was cheap steel and aluminum cased ammo.

I imagine a Just Right carbine is built to better specs than a Hi Point. I don't see how it could damage the gun at all, steel is harder than aluminum after all.

thanks for that ......i don't see what the issue would be
i have a few hundred rounds of the blazer but the handbook on the rifle says using it would "void" the warranty.......the only reason i could think of was case expansion issues which could possibly cause a jam ......if there is a legitimate issue i'd like to hear it .....i don't want to ruin the gun .....

Aluminum oxide is an industrial abrasive, used in many applications, including grinding steel. I don't know if the aluminum in the Blazer ammo is coated to prevent oxidization, but aluminum oxidizes when exposed to the atmosphere very quickly I have read.

Good luck.

Aluminum is coated with aluminum oxide. There's no way to avoid that, really.

I just had a CCI Blazer Herters .9mm split case in my .9mm carbine and seriously damaged both the receiver and the barrel.

Some years back we obtained a huge supply of Blazer 9mm & .45ACP with aluminum cases; we ran it through numerous weapons, both carbines (Uzi, Colt, Sten, MP-5) in FA, and some sidearms (Glocks, 1911's, BHP's, Fs-92, etc.), and never once experienced any issues. Even an old Thompson SMG ate it up. No problems at all.
Some time later I used a batch during a class at Gunsite, and never once had a single malfunction, misfire, jam, etc. This was using an old G-21 that was never cleaned at any time during the whole week. I have also noticed that when you are carrying a number of loaded magazines around, there is a noticeable weight difference as well.

I have had them split on me in a 357 mag revolver so I swore I'd never buy them again - this was in the early 90's. But I just got a new lever action rifle and wanted some 44 spl and the only option was Blazer so I tried it. 30 rds, all went well but I will always buy brass cased ammo if it's available.

A split case (whether aluminum, brass or steel) won't cause damage to barrel, receiver or breech.

A double charged round will, as would an out of battery detonation or firing a round with an obstruction in the barrel.

Do you have pictures and did you contact CCI?

It's not a matter of a split case.

It's a matter of a Blown case wall when the blow-back action starts opening before pressure has dropped enough for the aluminum case wall to contain it.

Brass is more elastic and will normally stretch almost like bubblegum before it fails and blows out.
Aluminum isn't as ductile as brass, and can just fail suddenly in unsupported blow-back chambers.

Personally, I would not use aluminum case ammo in a blow-back carbine.
There were industry warnings about its use & failures in blow-back operated SMG's causing damage & injuries a few years ago.

I had an aluminum Blazer burn through badly enough to score the chamber wall of my 1991A1 9mm. It had been exposed to smoke and steam in the house fire, but only enough to slightly wilt the box, and was not visibly corroded. I polished the chamber and pulled the rest of the bullets.

Before the Incident, I had been shooting it with no difficulty.

Thanks you have it exactly right. The fired split case fell out of my receiver when I disassembled the carbine . Both receiver and barrel are damaged.

I've shot tons of aluminum 9mm Blazer back when Academy sold it for the "everyday low price" of $3.86/50 -- not worth trying to reload for that price, never had an issue with it, but I'd never considered using it in a blow-back.

I think steel cased ammo is an improvement (I do use it without issues in my AR 9mm SBR and Uzi) over aluminum if for no other reason than that the cases rust away back to to dirt in 2-4 years, where the aluminum cases last until someone buries them or picks them up.

Huh? CCI Blazer is aluminum cased, and to the best of my knowledge, Herters is a steel-cased rebrand available from Cabelas. Regardless if it was steel or aluminum, a split case shouldn't have caused the type of damage you report

Years ago I had an aluminum case Blazer .357 case separate in a new Rossi 92 I had just picked up. Case head extracted with about 1/8 inch of the case, the rest stuck in the chamber. But a year or so ago (maybe a little more) I got two cases of .38 special Blazer from an online source for about $11 a box delivered. I've put about 700 rounds through my Taurus 85T so far with no issues, and this stuff is some of the cleanest shooting ammo I've ever run through that gun.

I've had Blazer aluminum cased ammo in a variety of calibers sitting around for many years with no evidence of corrosion whatsoever. It's always worked perfectly for me, but I've never fired it in any blowback operated guns, except for .22LR and that works well too.

I've shot a few thousand aluminium 9mm in my time. Some of my handguns are fine with it and some tended to stovepipe jam about 1:40'ish where they never have a problem with brass.

I've still got some which I now only use for practice and plinking. I won't trust it during any sort of competition.

I've shot a little 9mm in pistols, but my primary use of the alum cased ammo - when it was available cheap - was in 9mm & 45 SMGs. Never had a problem in Stens, MP 40s, MAC 10s or Thompsons.
IF I could still get it cheap I'd still be shooting it!

Herters is the house brand for Cabelas. Not all of it is steel cased, being offered in aluminum and brass as well.

CCI Blazer is not a type of ammunition, it's simply the economy line of ammunition from ATK (CCI/Speer/Federal/etc) Blazer is also available in brass.

Thanks for showing that to post #15. That is the product that exploded in my chamber.

Use it with a marlin camp 9 and you will soon need to buy parts. Not enough neck tension, so the bullet sets back, going up the ramp, then pressures go to high and the trigger group self expands and splits the (quite thin in that area) stock for you.

Save your money somewhere else.

Metric designated cartridges don't use a decimal point.
.9mm indicates 900 microns which is less than one millimeter.
