Fellow Savage shooters;

So I am torn between making a 6.5-06 or a 270WSM. I would like your opinions on either. I want to be able to take an animal out to 600yds. When I complete this gun and I get it to shoot .5" or smaller it will probably be used for my everything gun up to and including ELK mainly mule deer though. Before I get flamed for the last statement I am of the school of proper shot placement over "bigger is better", with that being said I like ft-lbs as well. I do have a 300WSM and a 300WM so I would appreciate it if people don't express stepping up in gun caliber. I love reloading so ammunition is not a factor.

If I go with a 270WSM can I make it a lighter rifle because it wont need a longer barrel? Which do you think will have a longer longevity barrel life?

Thank you in advanced for all you thoughts/inputs and I apologize if I offended anyone with my "don't express stepping up" comment. I am not an expert and have a lot to learn, I just know that I want either of the two stated cartridges.
