That 760 pump, and the 770 have absolutely nothing in common other than the name.
The 770 as mentioned is a piece of junk. A friend hunts with one and the trigger is horrible, the bolt is extremely sloppy, the bolt tends to stick and then if you pull on it hard it will pop out of the gun, overall, it's just a piece of junk.
Go with the Savage 110/111 for not much more. It's 50x the gun. If you can't swing that, you should be able to pick up a Savage Axis or Ruger American in the same price range as the 770 that are also much better guns.
