No flies on a standard 222 Mag. I have two of them, and accuracy is as good as it gets. Doubt that I'd ever "AI" either one of them. The 22-204 is essentially the same chambering as the 222 Mag.
Edit to add: Midway has 222 Mag loaded ammo made by Nosler. It is very accurate. I bought some and it shoots as well as any of my handloads for the 222 Mag. Also, Huntingtons.com has new 222 Mag brass. I bought a bag of 250 cases from them.
