All of the rifles you mentioned are quality firearms. I would suggest that you handle each and see how well they feel in your hands and when you shoulder each rifle. A rifle that fits well delivers recoil to your shoulder better and you will shoot that firearm better than a rifle that is awkward feeling in shooting positions. As for the 308 Winchester it is a good round. I do prefer the 30-06 but the 308 is nearly is as good. I prefer the 30-06 when shooting bullets heavier than 165 grains. Out of the rifles you listed I like the Winchester but the Tikka will certainly be lighter in weight. The 308 and 30-06 are not hard kickers in my opinion but that may not be the case to someone beginning to shoot. If I have any good advice it is to buy the rifle you like and feel the most comfortable with. This is the one that will make you the happiest in the end.
