Interesting. During the Obama shortage, I converted six Blazer Aluminum 45 Colt cases from berdan primer to large pistol boxer and then reloaded them in the normal fashion. Test fired all six cartridges in a Ruger Super Redhawk 454 Casull and half of the cases split 3/4 of their entire length. I completely wrote them off after that.I tested reloading aluminum cases in 9mm. I got 5 reloads from them before the cases stated splitting. Not hot loads just normal velocity 9mm. So I noted that 3-4 reloads on them is safe if one needs to use them.
Can you share the details of your experiment?
