I bought a case of this stuff based upon many reviews and for price. I discovered that it does not function well in three of my 22 auto pistols. Specifically, it does not run in my S&W M&P 22 compact, Walther P22 or Beretta 21A. The ammo seems to lack sufficient energy to blow out the spent case from the chamber. The ammo turned the above pistols into single shots.
Just for a point of comparison, all of the above guns run fine on bulk box Federal and even crappy Winchester M22.
I contacted the importer who advised me to have a gunsmith check out my pistols and magazines. I explained that the issue isn't feeding, they all feed the ammo fine. But, it seems to be the rounds just do not have enough energy. As stated above, these all run fine with other ammo.
On the plus side, I did find that the Aguila shot decent groups and functioned well out of my Ruger 10/22 rifle.
In the future I am only going to buy CCI. It costs more, but it works in all of my firearms. I offer this up in case you were considering buying a large quantity of this ammo and intended to use it in the pistols listed above. Overall rating: 3 stars out of 5.
