If you can find Aguila .22 buy it. I have had better luck with it working in ALL my .22's than with any other ammo, and it's usually pretty cheap. With the others, some works great in one gun, another in a different gun. The Mexican Aguila seems to work great in all 4 of my different brand .22's, rifles and pistols. It is as accurate as I am, and that's all I need, beyond function.
I must have 3-4,000 rounds of that stuff laying around here. Works great on armadillos, coon, possum and feral cats (the absolute WORST predator in the area).
