Thoughts on Aluminum vs Brass cased ammo?

Picked up a good bunch of Fed Aluminum 9mm. Will update if there are issues on the next range visit.

A co-worker bought a Marlin 1894 in .44 magnum and the instructions said not to shoot aluminum cased ammunition. If the gun functions correctly and you don't reload, I'd say shoot it. I did reload a boxer primed .45acp aluminum case just to see if I could. It shot fine but I don't think aluminum would hold up to repeated loadings.
