I've not heard much about this new round. If its a necked-down 22lr to accept the 17gr .17 bullet, I think that its already been tried a few months ago. A ammo manufacturer named Aguila tried this same setup or something very similar to it and it didn't fly at all. I think it was called the .17 Aguila. If I'm not mistaken, I posted a topic about that round on here back a few months ago. Is this "new" round the same thing?
