Yeah ya can! I've reloaded plenty of the Federals in 9mm. I load them about 3~4 times before trashing them. Just be careful on seating the primers, thats where you'll have problems.It should work fine. I hate aluminum cases, not because of performance but because I can’t reload them.
Thats my one and only worrie about the aluminum casing .A guy on Sig Talk had a potential problem with Aluminum Fed 40 with a P320
Seems as though a bad detonation cracked the casing and blew out the extractor and cracked the grip module.
Sig said it was a bad round and Federal says the gun fired out of battery. Sig fixed the gun and Federal gave him new ammo but he asked to replace it something other than Aluminum.
This happened in February or March of this year.
