The CCI Blazer aluminum cased center-fire ammo has been good in all the calibers that I've tried. Never had a single issue with one of my handguns. At one time I bought it because the aluminum cased Blazer was cheaper than other factory ammunition. Those days are gone. As well since I reload, brass cased ammunition is more attractive to me as the cost difference between the aluminum cased Blazer and other domestic brass cased ammunition seldom outweighs the price of actually buying brass for loading. I have not ever used any aluminum cased Blazer .22 LR ammunition. In fact I don't know that I've ever seen any of that particular load. I have shot a pile of Blazer brass cased .22 LR ammo in a variety of rifles and handguns. Results have always been extremely good, fully the equal of any other quality .22 LR ammunition produced by either domestic or foreign manufacturers. I first started shooting the Blazer .22 LR ammo back when the first ammo shortage occurred as a LGS would commonly have it in stock at a reasonable price. I had up to that time shot other brands of .22 LR ammo, mostly various HP loads w/ copper washed bullets. Now in this period of a renewed shortage of .22 LR ammo, I have been able to find some .22 LR Blazer ammo available for sale at less than nose bleed prices. I have been buying it every time I see it out for sale. It is very excellent ammo.
