Picked up a CZ 452 American slightly used (80 rounds) here on the EE a few days ago. I resisted the 17 HMR craze for quite a while, but finally caved in. I mounted a Bushnell 6-24 Banner D to D on it, installed a Brooks trigger kit and took it to the range. WOW! is all I can say! This little rifle is impressive. I tried 5 types of ammo, and none shot badly. What really shone was the Hornady 20 grain XTP ammo, with 5-shot groups around 3/8 inch at 50 meters the norm. I also shot a couple of sub-MOA groups at 100 meters with the same ammo and one group right at 1 moa with the CCI 17 grain V-max load. Hard to argue with those results. Me thinks the crows may take a beating from this little rig. Regards, Eagleye.
