re: Getting into deer hunting, need a new rifle. Sell me on your favorite

You would do good with any of the 308 rifles mentioned. I would spend $$ on excellent scope rings (Leupold or other high end), and then get the best scope your budget allows. Also, I would let a gunsmith mount the rings and scope and bore sight it for you. That should get you going with a rifle that’ll shoot much better than you for quite a while.
