RE: First real rifle - mostly for dear, What would you get?
Tell us a price range if you don't mind, may help because there are a lot of rifles out there.
If it was me I would go with a Remington 700 on a mild budget or a Kimber 8400 not on a budget.
Caliber for deer.. 243, 25.06, 7-08, 270, 30.06... depends on what else you want the rifle for and what type of hunting you will be primarily doing.
