Got a cheap shotgun when I was 12 years old, all my parents could afford. Shot a limit of dove with it this past season…I’m 56.
Cheap needs a numerical value I guess…I consider a $600 or under rifle cheap and while I haven’t reached 20yrs with it, it still shoots as good as the day I put a Leupold on it. In fact she was used this past season on some does from 25-275yds with one shot kills.
In response to the OP’s post, he probably needs to buy a precision rifle if his son is wanting it for competition or only long distance shooting. And he’ll need some nice expensive optics. With his budget, I’d go with a cheaper rifle and nicer optics.
