My father has just started getting my younger sister (12) interested in a competitive small bore rifle club. We are trying to find a good rifle for her that she will be able to use, without growing out of it, shes about 5'. I am looking for a good target 22, single shot, with micrometer sights, i have never really dealt with it, I am just looking for suggestions, and recommendations as far as rifles and equipment that would be good to help them get started. Thanks in advance.
