I suspect that Blazers are factory seconds of the CCI ammo, as most big box store promotional ammo is, from the other manufactures. Seconds does not necessiarly mean junk, as it can mean the velocity spread is outside the mfg's standard, or one lot is a few fps slower or hotter than what the standard is also. Could be it shoots one inch groups at 50 yards instead of 1/2". Sometimes you can hear variations of the report when fired also when the variation of velocity is great. They don't want to sell this out of spec ammo under their premium label, so they repackage it, and sell it at a discounted price. That's my opinion anyway. I have been told that, often match ammo is selected lots of regular ammo, that displays exceptional accuracy and uniformity.
