Chief Dave on RimfireCentral's view is - "Bwahahaha!" He's about as well up on the rimfire industry as anyone, and has been hearing this for a couple years - he tells us to believe only what we see. Aguila has a bad habit of announcing stuff that never comes to market.
That being said, I do like their ammo that is making it here. I commonly use the 60grain SSS, the little Colibri and the SuperMaximums. If they bring in the .17, I'd get a rifle for it.
