Not so sure about my Sig 50-500:-(

I am new to this site,and pretty new to Photography.
I have been shooting for almost two years and am still struggling. I have the K-10 with a Sigma 70-300,Pentax 18-55 and the Bigma.The majority of what i use this camera for is widlife, I have a FZ20 for just shooting around the house. Anyway I am not getting very good pics when I get into the 300-500 range,which is very frustrating because I bought this lens for that reason. I am wondering if something is wrong with the lens because I can take a picture at 500 free hand,and see no difference if I put it on my tri-pod. maybe I am expecting to much from this lens? The pictures are great at a close distance 20-30 yards but awful at 100+.

I really don't see anything wrong with your >100 yard shot.

You have to remember that DoF is affected not only by your focal length, but by your proximity to the subject, as well. The only thing I can see in your >100 yard shot is that the background is distracting, because of the lack of bokeh.
