The only Blazer I've ever shot is a box of 38 Special aluminum crud I bought back in the late 80's and wasn't impressed at all with it. Some of the absolute dirtiest ammo I've ever shot. But that's a long ways between then and now, and I don't hold that over on the Blazer Brass ammo. But I just don't shoot factory ammo. I do know the 9 MM Blazer brass cases reload very well and seem to hold up though. If I had to buy some store-bought ammo to run in my pistols, I wouldn't turn away from the Blazer Brass stuff. But I refuse to waste money of the aluminum cased stuff since the cases aren't reusable.
