I've been thinking about this for a bit.. I agree the 270 is a great deer round, super easy to find ammo and dirt cheap! but if I could only pick one rifle to hunt deer with I'd have to go with the 7mm mag, short or long. Pick what ever rifle you can afford or like (I'm partial to Remington 700's) and a good scope (I'm partial to Leupold's, rest is decent but not good enough for me) and practice practice practice. This is 30+ years of hard hunting and guiding talking.
