I have one in .204. It's a sicko...tight groups with the right ammo, handles bautifully. I have the Varmint model with heavier barrel...I don't know if I posted it on here or not, but a few weeks ago, I took it out to try to find out which ammo worked best in it...Hornady, Remington, or Federal (all 40g stuff), and found that I could get a little tighter than 1/2" 5 shot groups with the Federal stuff. I was in a predicament as to which sub-caliber rifle to buy for a long time. Ordered a custom AR...guy didn't come through, so I took to Scheel's for some time fondling several rifles, and ran across the 527 Varmint in a used rack at another gun store...ordered a new one about a week later. I'm super glad I did, I can't believe the guns accuracy and SWEET trigger. I have two regrets about the CZ; 1. I wish I could have found an American made rifle that I liked as much. 2. I wish I had gotten it sooner.
