I loved the 06... love my 270..... my 308 is my new love.That cartrige will do everything I need and for my needs will probly do it better than the 270 or the 06...That said I hunted with 760 pump 06 and model 700 in 06 for better than 20 years . Got a smoking deal on a 270 winchester barrel for my pro hunter so I messed around with it .... great gun if you hunt open grounds ... big farm fields power lines or gas lines.... not so good in brush... but the 308 does it all with less recoil than the 06 and bullets dont decinigrate on bone or from hitting a twig like the 270.... yea I know its the bullet.....not having that conversation ..I honestly like the 308 for my type of hunting.300 mags ... why????? 270 short mag why again ???? why spend twice the money for ammo .Honestly 06 surplus ammo is way harder to find than 308 these days. Short action verses long on a deer rifle ... not even a concern for deer hunting ... maybe if i was hunting lions in africa ....big tuskers or black death...
