Great ammo compared to steel - Federal Premium Centerfire Handgun Ammunition 9 mm Luger 115 grain Full Metal Jacket Centerfire Pistol Ammunition, Aluminum

This is great ammo if available, it functioned flawlessly with all 9mm guns my family and I own. aluminum cased doesn't cause any of the extra wear and carbon build up like steel cased does in fact a better comparison is it felt and ran just like brass cased ammo. The only difference I notices between this and brass cased is aluminum cased ammo cant be reloaded if you're into that. Other than that it performed exactly like brass cased.
