Go to the auction sites and look under Savage over and unders. I don't think they have been made in years. The best of these are the .222/20ga. Tons more are the .22lr/.410.
Search the net for Savage 24. They come in different combos .22/.410, .22/20ga., .223/12ga. ect. I have a 24F in .223 and 12ga. and it is very accurate, and they are usually pretty cheap, for the type of firearm. Good luck.
I have the Savage model 24F (I believe) in 22 hornet/20gauge.
It is a great turkey gun and same goes for varmints.
The only thing that I did not like was the trigger, it was pretty bad, but a gunsmith smoothed it out and it made all the difference in the world.
Still has a heavy pull but breaks clean now.
