Right now Natchez Shooters Sports (https://www.natchezss.com/) is selling Blazer 9mm 115gr FMJ for $4.99/50-round-box if you buy 20 or more boxes. I've been tracking 9mm ammo prices at various websites and in stores here in San Antonio in anticipation of making a bulk buy of practice ammo, and that is a great price for 9mm. So I ordered 40 boxes. With shipping, that works out to just over 11 cents a round, which is quite bit cheaper than the others.
I've read a couple grumbles about the aluminum case at other forums, but I've tested this in all my 9mm pistols, and it shoots well. I sent back one pistol for warranty repair that had all kinds of problems ejecting other brands' cases, but it always cycled Blazer properly.
Plus, I don't mind leaving the aluminum cases behind at the public range. My reloading habits taught me to save my own once-fired brass -- Altho I don't reload 9mm, it always grates on me to not be able to pick up and save my own once-fired brass. With aluminum, I don't care.
