in the real world both are damn good calibers -- the 308 would win points for being able to be produced in a shorter action than the .270- the 270 would win with an increase in its knock down ability - for me given the choice having used one the mighty .270 - in saying that 308 is my go to rifle - both have easy availability of ammo if you are not into reloading - many whizz bang calibres these days are just for reloaders - both have good resale - some of the modern whizz bang calibers very difficult to resell if you decide to change - now what you will get on here is a whole lot of they are old calibers this is better and so on - take no notice either 308 or 270 is a great caliber and the deer you shoot certainly wont be telling you which is better - pick your favourite shooter and get out there
