Aluminum cased 9mm?

One thing to watch for is the case is lighter so it can change how the cases eject. I have a Girsan 28 and it fires Aluminium fine but it ejects straight back and up instead of the side and up with brass meaning you get hit in the chest with the spent cases and that can be annoying.

thats no joke. i put some of it thru an M1-9, and caught a lot down the back of my hoodie.
 
I don't buy aluminum cased ammunition anymore. Also per the instructions in the manual DO NOT PUT ALUMINUM CASED AMMUNITION IN THE FX-9

Or This Can Happen

I'd rather pick up brass and wash it than even consider using this type of casing as a reload.

While I haven't shot 9mm with an Aluminum case, I have shot lots of .44 Magnum with Aluminum cases through my S&W 629 and never had an issue. Never tried to reload it so I can't comment on that. Also, I've shot loads of Steel cased ammo in 7.62x39, 9mm and 7.62x25, and none of my guns are worn out yet.
 
Clean the chambers of any firearm that has been fired w/ aluminum or steel case ammo since the aforementioned will not seal the chamber as brass cased ammo will.

Steel "projectile" ammo will wash the rifling out of a Bbl faster that jacketed ammo.
Some steel projectile ammo will have copper washed projectiles to prevent corrosion....touch them w/ a magnet.

You have a serious feed ramp issue to be cutting aluminum cases as pictured.

...There is either steel core projectiles (That have a steel penetrator surrounded by lead), or bi-metal jacketed projectiles (Which is a steel jacket plated with copper). No bullet that exists for use in a standard rifled barrel will have steel exposed to the rifling of the barrel. A bi-metal jacketed bullet might wear the rifling out faster due to the layer right under the copper being harder, but the steel is never directly in contact with the bore.

That's pretty gnarly. Do you know what was causing this and why it doesn't happen with brass ammo?
