Aquatech, I've had the exact same problems with My Knight I purchased several years ago. I have tried EVERYTHING powder and bullet wise and can't get it to shoot for anything. Even went so far as to try two different scopes and 2 different mountings. Same results. Talked to the Knight reps at the Shot Show last year and they told me to send the rifle back to be worked on. Haven't done so yet and thinkI'll just buy an Omega.
