I have no experience with Aguila products so I have no idea how accurately they will shoot, especially in your guns. As far as reliability goes, I do have a few friends who use Aguila and they have nothing bad to say about the ammo.
As a long time competitor in many phases of shooting, I want my ammo to be the most accurate I can buy as long as it is consistent, reliable and is readily available.
I use two hand guns for competition. One is my S&W M41 and the other is my M18. I fond that in my M41 the absolute best round for me is CCI 40 grain standard velocity. For my M18 I find the CCI Mini Mags (high vel.) is what works best. To me, I don't concern myself about the 2 cents a round difference as I am more interested in the performance. If you are the type of shooter that only shoots steel plates, combat silhouette targets, etc. it probably won't make much of a difference since almost any 22 ammo will shoot good enough for that. My personal interest is in precision and consistency.
In my bolt action scoped target rifles I also use CCI Mini Mags, but if just at the range and plinking with a pump or lever action I will use Federal #510 (blue box), American Eagle 40 grain High Velocity or what ever I have in stock. Out of my CZ 453 American (I use this for rifle competition), nothing shoots as well as the CCI Mini Mag with the Federal Blue Box not far behind.
