I ordered 2 bricks because the AA kit for the Glock recommends them.mopar guy said:They're not the greatest. "Hot" loads don't necessarily mean "accurate" loads, and that pretty much sums up mini mags. Check out your gun store and ask them for high velocity target 22lr and there should be a few choices even cheaper than the mini mags that will perform much better.
That being said I bought a case of them for my Kimber 22lr conversion kit. The slide needed the extra kick to cycle properly, in such a case the mini mags kicked ass...
