Like the one earlier post. Don't be afraid to check out the used rifles. You can save a lot of money on the rifle and put it toward a good scope. And this time of year is perfect. Some guys just trade their rifles in for something different. And there is absolutely nothing wrong with the one they traded in. A lot of the models previously mentioned will fill the bill nicely. But YOU need to be the deciding factor. Which one feels best to you. YOU have to be confident in your rifle. We can guide you but the choice is ultimately yours. As for chambering - anything from .243 up will suffice. My personal favorite is the 7mm-08 Remington.
