Can't speak to anything but their .22 LR. I've shot their standard velocity LRN and personally have found it very accurate. I've also tried their 60 grain Sniper SubSonic ammo and it groups pretty good. Shoots very low if you're sighted in with 30-40 grain bullets tho. Really needs a dedicated rifle set up for it to maximize effectiveness.
Also, in all the .22's I've shot it from, both pistol and rifle, the SSS doesn't keyhole even though Aguila recommends they be shot from a barrel with a faster twist.
I've tried their Super Colibri and I think it's a gimmick. I think one would be better served using a .22 Short for pest control, it's just as quiet and much more accurate and powerful.
So far I haven't been disappointed in their .22 ammo and I like the way it smells when I shoot it.
