Not sure if they are in some way related to aguila ? But my experience with Mexican 22 is that it is better quality than all American brands with exception of CCI.
I remember seeing some of this during the shortage, but never got short enough in my supply to buy any.
It is pretty sad that federal, Winchester and Remington can’t produce any 22LR of decent quality. Federal is sort of marginal and if I get it at a good enough price will still buy it, but won’t shoot Remington or Winchester unless I get it for free, as the quality is that bad.
