the .308 will do the job in North America with the right bullett. less recoil will also assure a better shot, making a more effective choice. I am 55, have no use for the magnums, wsms etc. unless you are a lemming and just got to go with the crowd. .308 ammo is sort of abundant nowadays compared toa few weeks ago. the magnums and wsms will put a hurt on your wallett. just some advice from an old hunter with no sore shoulder, good accuracy and not a lemming.
