Thread: .308 or 7mm 08? Newish hunter for deer/tahr

Hi,
I'm sure 'what rifle to buy' is well worn question here, but I couldn't find an answer....
I have some hunting experience but haven't owned a rifle before.
Currently leaning towards a tikka 308. Seem like a light accurate rifle and a calibre that is well proven and will do the job on any hunt, plus wide selection of available ammo.
However if what I have been told is right, the 7mm 08 has better long range shot credentials...or Tahr or longer range shots it may prove useful?
I must say when look at the barrel length of them side by side the 7mm is vastly longer which makes sense in my mind for accuracy of distance.
Any feedback will be gratefully accepted.
Thanks
