I want to do a poll with opinions. No bashing someone's opinion unless they say 6.5 as an option. Which of these four calibers would you choose and why? Looking at what you feel is the best all-around. .270, 30-06, 7mm or 300 win mag. Say nothing about accubonds, mystery ranch metcalf or leupold. I know there has been similar threads comparing one against the other.
