I tried reloading them one day just because I was bored.

It didnt turn out well.
first off, I would say 10% of them wouldn't even hold a new primer, the pocket had grown so much.
second, another 10% would split with you flared/seated the bullet.
Then with the ones that looked ok, 50% of the primers would come out on firing, and about 25% would split on firing, and this was with way way way reduced loads.
I definetly think the NR on the bottom of the case is well granted. If you reload these and shoot them, expect major case failure at some point and possible harm to the shooter and people around him/her. I wouldn't shoot beside someone using reloaded Aluminum cases, thats for sure.
