Hi Kar,
Welcome to GBO!
I agree with Grumulkin specially the Contender/ reloading issues,,,,With your situtaion of no reloading, the 7-08 is a great choice. In a 20" barrel, give or take a couple inches, I can't think of a more practical round. And should you have the oppritunity to travel for larger species such as Stag, you'll have enough gun for that too.
Encore 7-08, be my choice in your position.
Dave
