pentax 55-300 out of focus

Oh, ok, I missed that. Next thing to rule out is front/back focusing. It's hard to tell with the subject you've chosen. Make sure you also try manual focusing with live view at high magnification.

The person I bought from has promised a full refund but I am just shocked that the picture could be this bad any comments (this is a 100% crop)

Let's assume you are not a total incompetent - the lens is clearly b*ggered. My first 55-300 performed like that after I dropped it. Warranty obviously didn't cover that, so I paid for Pentax to fix it in Japan. It came back only semi-fixed, but allegedly (as I was told after I sent it straight back with a protest) "within spec". I bought another one as part of a kit with my K-x. Somewhat better, but still not as good as the first one was originally. It's a lottery, folks!

But that photograph is clearly the product of some kind of malfunction.
