Your first CZ rimfire rifle? Be warned, they multiply .. just like the jack rabbits ... LOL
My Scout has been sitting idle for 1+ year.. took it out a few weeks ago.. the tightest 5-shot group @ 50 yds was 0.15" with Eley target, next up is 0.22" with Wolf Match Target -- of course, some groups are in the 30s, 40s, too, but none the less, it was a very good day.
Enjoy your new toy.. (and make room for more 452 / 453 / 455 .... )
