The cons are,recoil,very expensive brass and loads,and short barrel life.In fact if it is your primary rifle and you use it to practise enough to learn and to actuallytake advantage of the super flat trajectory,you will be rebarreling it every few years.If you don't practise regularly,you will never develop and maintain the shooting skills necessary to take advantage of this cartridge.It is a poor cartridge choice for a one gun hunter.
