Default Canon EF 100-300mm Lens shot

Here's a 100% crop of a shot I took at full zoom on my 100-300mm lens. The picture is effectively shot at 460mm on my APS-C body. Is this level of detail on par with other lenses at this focal range?

The picture is of the Crazy Horse monument, seeing a bit of the face and handrail across the arm.

This is the level of detail from the EF 70-300mm at 300mm

The Canon 100-300 USM isn't very good at the long end, and it's not stabilized like the 70-300 IS USM that shoturtle mentioned. I believe I see a little motion blur due to camera shake. The vertical portions of the handrail seem sharper that the horizontal portions, and that would be from camera shake.
