There are many variables to consider such as expected shot distances, cover / terrain, quarry. Either of the two mentioned is more than adequate to kill deer. The good ole' 30-30 with LeverEvolution ammo will do well out to two hundred yards or so. The 06' further but with more recoil. You just need to hit a LGS (or two) and shoulder several rifles and see which one feels the best to you. I'd say a Marlin lever action 30-30 with a fixed 4X or 2-7X variable scope would be a good choice.
I can easily go 200 yards with flat nose 170's. I've done it. Leverevo's push things to at least 250-275 yards.
