Depends entirely on the rifle. You may find a used bolt action .22 in fair condition for $50, or pay $2,000 for a new, high end match grade target rifle. Sort of like how much is a car? Depends on the car. Your best bet would be to visit a local gun shop, and talk with the staff. A rifle that is good for hunting small game or informal target shooting (plinking) should run around $125-$150 or so.
22 hornet is a 22 calibre rifle. Most think of a 22 rifle as a rim fire rifle. But it shoots a 22 calibre bullet but the cartridge case that fires the bullet is no where near the same. The Hornet holds much more powder and is center fire.
