Just check out all the models and see which suits you best.

Can't go wrong with either the .270 or 30/06. Ammunition is cheap and available at every podunk outpost you can imagine. Good killing power to 300-400 yards, easy kills to within 200.

Practice, practice, practice, good reason to go with the traditional .270....or 30/06.

I have one of each, can't go wrong.
