I'm a new rifle hunter; just bought a Ruger bolt action 30-06. It appears that there's quite a variety of ammo for a 30-06 (one reason why I bought it). As a newbie, I need some feedback as to how to pick from the choices of ammo (gr. of powder, type of tip, etc.). At this time, I expect my use of the rifle to be limited to whitetail, out to about 100yds. Thanks.
