What are the pros and cons of aluminum case ammo ?
My Charter Pitbull doesn't like it. They won't eject well.It was supposed to be less expensive.
But, it doesn't seem to have made a significant difference compared to similar brass cased basic practice ammo.
Some guns don't handle it well. Same can be said for steel case ammo. Hard to predict without testing. Sometimes ejection issues.
Some greater risk of case rupture with some blowback weapons such as submachine guns.
That's my $.02 and experience.
