Ok I was about to purchase some American Ammunition Alpha Delayed Expansion 115gr. 9mm ammo today but know nothing about them...heck I never even heard of them. Can anyone throw some info on this 9mm round made by them my way? Ballistics? Expansion? Did a branch of the military use them? I was told they were but I want to know more then from just one person. Also was told they start expanding once they leave the barrel...any confirmation on this? They look very nice and look like they can be used as decoration instead of being shot lol.
