Might be worth trying with today's lack of components? Several years ago I did an experiment with aluminum cases, 45 ACP Blazer. I checked each case for a single flash hole and reloaded some. Most made it through the second reloading, some to the third. Aluminum necks split easily and neck tension varied too much for me. Other performance (feeding, firing, extraction/ejection) were OK, but only tried reloading 3 times per case at the most (a good percentage didn't make it past 3) and could see damage to rims. I have records somewhere, but I also have three shoe boxes full of processed 45 ACP brass and a coffee can full of once fired, along with about 1,000 JIC handloads, so I don't even think about aluminum cases...
