My CZ 455 in .17 HMR, CenterPoint scope. It now has a BSA Sweet 17 on it, but the CP was available at the time I bought the gun.
When I bought the gun, I stopped at a spot in the desert that locals shoot at, to try it out.
Ran a patch down the barrel, came out clean.
First 10 rounds, I shot 5 to check function, get a feel for the trigger, and warm the barrel. Then shot at this target, bottom left, then clockwise. 1 shot adjusted, 1 shot adjusted much more...then 3 more shots. I was impressed, never shot a .17 before.
This was at 25 yards, front arm rested on the bed rail of my truck.
