I always want to try something new when it comes to reloading. I tried reloading steel cases when many did not think it could be done. Now many people do it. I was at the range today and noticed some alum blazer on the ground. 9mm and 45. I looked inside the 9mm expecting a berdan primer system and was surprised it was boxer. Same with the .45, but it uses SP primer instead of LP
So i took them home and sized them and primed them on my press. put a bullet in them to check neck tension. They seemed to be just like brass. I have not loaded any with powder yet as i want to see if anyone else has done so here.

Quoted:
I usually save up 500 - 1000 of them, reload them once and leave them at the lost brass matches. I do something similar- I load'em up for my Brit friends when come over for a taste of freedom. That way, I don't have to go searching for brass (but I usually do anyway, cuz once a brass whore, ALWAYS a brass whore.  )

Somehwere in the neighborhood of 6-7yr ago.. did it as a Glockpost topic I think it was..
Fired some in my M11-9, and then into the GLOCK 17.. most were split after 2nd handload firing, about 1/3 split on the first handload firing. Use them for last ditch ammo, or at a match where they keep the empties if you comfortable with reliability of loading/firing at match. |

aluminum will fatigue crack without being over stressed.
When you fire a cartridge, it yields and forms to the chamber. When you deprime and resize, you yield the material back to its original size. you cannot anneal aluminum to prevent this. its the nature of the material. My concern would be case splitting or head separation when its fired the second time. |

I am the kind of guy who, if told it can't be done, will try to prove them wrong.
That said, don't do it. I did not say it can't be done. Those cases will fail by case body splits on the first or second reload. The bad part of it is that you will see a large washed out area at the bottom of the split. That washed out material was aluminum, jetting through your gun's moving parts. That aluminum will quickly oxidize to Al2O3 crystals, one of the best abrasives on the planet. Do you really want that on every sliding surface of your gun? |
