Why? I mean the cases seem durable, they appear to be some kind of alumininum alloy. Just for fun I ran 7 cases through my sizing die and they felt like a brass case. They flared properly with no splitting or abnormalities. I put in 4 grs of bullseye behind a 200 gr swc cast bullet.
They do use a small pistol primer instead of the large though..
 
hmmm the small pistol blazer brass I found at the range looked like brass to me, ran 50 though the sizer, no problems. Havent loaded it yet though.
 
People on other forums have said they did load them once or twice. There are even people who have reloaded steel cases like 7.62x39.

Whether it is a good idea or not will likely lead to debate.
 
We might be talking about two different Blaser cases. The older non-reloadable Blaser were aluminum and used a special primer pocket and primer size (I think they were Berdan style). They could not be reloaded without a lot of work in the primer end. If the cases you have can be reloaded with a SP primer easily they have either changed the product, or they are the new brass Blaser which appear to use the normal SP primer.
 
I think a closer look at your cases will confirm that if you did infact reload them they are brass cases. I'll guarentee you did not reload aluminum alloy cases cause they are in fact Berdan primed.

What about the dies ? Isn't AL somewhat abrasive ? I committed to a bunch of this stuff "Blazer" a few years ago before realizing what it was. I wouldn't put it through anything but a "plinker" grade pistol let alone my Redding dies. If I'm right, I'm sparing my gear from early ruin. If I'm wrong,, "so what"?
 
Aluminum isn't in and of itself abrasive, but being softer, it's more likely to get grit embedded in it than brass.

Blazer, IIRC, was originally introduced as a cheaper alternative and was deliberately made to be non-reloadable due to legal concerns. I could be wrong.
 
Well they worked without a hitch! I only loaded 7 rounds just to see and they weren't berdan primed but they were the aluminum case.
They weren't as accurate as the bras RP cases I loaded with the same charge of 4 grs of Bullseye under a 200 gr swc cast bullet.
I'm guessing the small pistol primer may have made the difference.
I also checked the case length after the 2nd firing (first being the factory load). The cases needed trimming as well, so they do stretch quickly.

I have come across both berdan and boxer primed Blazer alum cases. My 10mm are berdan for sure.

The issue is that alum alloys don't stress cycle the same way brass dose, and will fail sooner. The fact that they stretch so much should tell u something.

With pistol brass so readily available I'm not sure why anyone would bother.
