Fired many thousands of 9mm and .45 Brass-case Blazer in a variety of guns. The cases reload well.
Recently CCI started giving Blazer it's own headstamp (Used to all be CCI headstamp, now there is a BLAZER headstamp).
The cases are consistently the cleanest cases after tumbling. Very little residue.
The aluminum stuff shoots well too, I even had a couple boxes in .44 Magnum that I shot a year or so ago in a Ruger SRH and it was fine.
I reload everything now so I only buy factory .22's.
