I have fired several thousands of CCI Blazer rounds in calibers 9mm, .38 special +P, .357 magnum, .44 special, .45LC, and .45ACP, including FMJ and JHP bullet types. In my experience with this ammo, it happens to be one of the cleanest, making for quick and easy firearms cleaning. It has also proven to be very reliable. It is an excellent choice if you are looking for economy but there are more accurate brands of brass-type ammunition. I continue to use Blazer, in addition to other brands of brass-type ammo.
