Wow! beats all other 17 hmr ammo - CCI Ammunition A17 .17 Hornady Magnum Rimfire 17 Grain Tipped Varmint Rimfire Ammunition

It might be optimized for the Savage A17, but it's the best stuff I've tried in my CZ 455 too. The accuracy is great but not really any better than other brands. My rifle shoots them all under an inch at 100 yards. What's outstanding is the velocity. I've chronographed it at 2874 fps over a 12 shot average... over 200 faster than advertised. I usually shoot Hornady which averages 2670 (2550 advertised) but the A17 is another 200+ faster. Equal accuracy with much greater velocity, less drop, less drift, and more range... It's even cleaner than the other 17 HMR ammo out there. Can't ask for more. I'll definitely be getting more of this.
