Would 100% echo the sentiments of the CZ 45x series. I taught two of my kids how to shoot with a bolt action .22 (unfortunately I did not have my CZ at that time so the Savage had to do). The other advantages of a .22 are somewhat still widely available ammo, and most importantly, it is still relatively cheap in comparison with a number of centerfire calibers, all of which have ballooned in price and shrunk in availability. 22LR will allow sufficient practice, there is virtually no recoil so very friendly to new shooters.
The CZ 452/455/457 are all excellent choices not just for the new shooter, but for shooters of all skills, backgrounds, etc. In fact, I am taking my 457 this weekend to my club and will be target shooting with it predominantly. It is a very enjoyable rifle, and great accuracy out of the box.
