pretty sure you'll get them stuck in your dies on the first try. Alum cases are severely compromised after you shoot them once. Al corrodes exponentially faster than steel in high heat environments. When you expose Al to heat Oxygen and Sulfur and Carbon, especially when it is so thin, it's pretty much FNG (F..... No Good).
If you're extremely careful you may be able to reload them, I know you aren't supposed to, don't know why you would want to, I've had new ones rupture in my guns before, nothing huge but it's a PITA to get a cracked Al case out of your gun after it has flash welded it's self in.
I despise them myself.
