Good info. Thanks. I've fired more than a 1000 rounds of the stuff with no issues.FYI, ran some of this over the chrono. From a 4.9" Beretta, it averaged 1123 fps. This is within about 5 fps of the Fed Champion that is also sold at WalMart (though tested on diff days). So it's pretty normal plinking stuff, just cheaper.
The Federal Aluminum has only been out a year or two. Blazer Aluminum 115gr only goes 1065 fps when I tested it. It's not a huge difference, but it made Blazer Aluminum the weakest commercial 9mm ammo I've tested in terms of muzzle energy. And while the actual difference might not be that much, 320 ft-lbs of energy sounds a lot better than 290 ft-lbs.I have shot aluminum cased ammo for years and it is fine.
