The Mossberg bolt-action is much better than the 770, and is about the same price.
I agree that the 770 is not worth keeping, even if it were a gift from your dad.
People are like rifles. Some are tried and true, having great eyes, personality, and fun to be with. Others never seem to hit the mark with you. Still others go off half-cocked. Still, it's nice to know most of them.
