Since no one has voted on a shotgun, you can still go back and take off those options. You don't need to get angry, there's always the crowd that if you have a poll like this and say, "what's you favorite caliber?" they'll say, "A caliber is the diameter of the bullet, you're referring to a cartridge."
They're not wrong, but anyone who's been on this site long enough or gone through Hunter's Safety knows that already, so after awhile, it can get annoying.
Just learn to get used to it, it won't pay to keep getting frustrated, humility can really pay off here, even if it's hard, and I've failed sometime at that.

You might want to put the 7mm-08 up there, and the 7mm Rem Mag, which, actually, I think is better than the '06 for performance, the 7mm Rem Mag has higher velocity, and can shoot longer range than a 30-06, yet it has about the same power at 100 yards, 7mm Rem Mag is just more versatile for long-range shooting, I would much rather have a 7mm Rem Mag with a 4-12x40 scope on it than a 30-06 with a 4x12x40 for hunting Mule Deer in the West.
