The Ruger 10/22 is the most popular .22 rifle in America for many reasons. If you want it to work like a bolt action instead of a semi-auto just buy the very low powered ammo like CCI CB caps or Aguila Colibri .22 ammunition. They don't have enough power to work the action so you have to do it manually after every shot. The ammo is also very quiet and about like shooting a pellet rifle. A lot of the small bolt action .22 rifles have terrible trigger pulls which is really discouraging to a new shooter and a 10/22 has an incredible amount of aftermarket parts that allow a lot of flexibility and it can be configured almost any way you want for a fairly reasonable price.
