There's a Yukon Youth drop breech in the Traditions Bargin Bin right now for $109.95 that's an online only special.
The length of pull is 13.25 inches which should be perfect. And the Yukon action is a clone of the Remington Genesis except it has a 22 inch barrel.
It comes with a free rifle case too!
