Bamashooter is right
I had a buddy with the Savage automatic. It was very cheap. It shot OK, but was just really cheezy, the way he had to push in on the bolt handle to lock it back.
The Ruger 10/22 is also not that great to lock back.
The Marlin 60 is the best bet, IMO, for an automatic 22. I think their bolt guns are nicer than Savages in 22 too.
Expand your search outside of Walmart.
Another thing about the Savages is that all they have are the box magazines that stick out the bottom of the stock, right where you may want to rest the gun some day, while the 10/22 and Marlin 60 do not.
