RE: Is there a "good cheap" bolt .22 rifle?
All modern American Made rimfire rifles will hold a 1/2 MOA at 50 yards - right out of the box.
My friends recieved Marlin .22's - Glenfields - that were sold at KMART for $49 back in the 70's that would hit a dime at 50 yards religiously.
30 years later, they still have the same accuracy as they did the day they were brand new.
