Cocojo;
Federal, CCI and Blazer are all owned by the same parent company, Vista Outdoor. That Federal Champion Aluminum Case ammo at Wal-Mart is specifically packaged for Wal-Mart and nowhere else, it has a product number that begins with "WM".
Now, take a look at the Federal Champion brass cartridges-- they are extruded, exactly the same type of brass that CCI Blazer Brass uses, and notice that Wal-Mart doesnt carry Blazer Brass any more. And the Fed Champion brass cased ammo comes packaged in the exact same white plastic trays most recently used with CCI Blazer Brass.
So Vista Outdoor owns CCI, Blazer and Federal . I have heard that the Fed Champion Aluminum Case and the Blazer ammo product lines are streamlined and manufacturing of these products is now combined. But I don't know that CCI ammo is going to cease, or even that Blazer Brass is going to cease...
But that Federal Champion Aluminum Case ammo at Wal-Mart looks to me like Blazer Ammo in a Federal box, and as I mentioned earlier, I'd be willing to bet that Vista Outdoor is simply consolidating some of their products.
Sorry to hear about your problems with your LC9. I'd recommend that you don't shoot any more Blazer Ammo with it. For the record I've shot Federal Champion Aluminum Case ammo from my Glock 17 & 21, my CZ-75B, my HK P30 9mm and my HK45, my Sig P225, P228, and my P-226-40, and my BHP 9mm. Never had a problem with it in three different calibers.
