It doesn't matter which one you pick. When it comes to deer hunting the 308 and 30-06 are virtually the same thing. However, you will probably find more light weight rifles available in 308 than 30-06. My personal pick would be a Browning Micro or Remington Model 7 in 308. Find a rifle that you like, at a price that you like, then purchase which ever round is available in THAT rifle.
