Listen to Ron and Sabot they are very knowledgeable.
Personally I have shot TC guns since they first came out with the Hawken at the moment I have 6 the two you would be interested in are the Endeavor and the Pro-Hunter both are excellent rifles I automatically change the trigger spring and use a +1 pin but that is not normal for hunting accuracy unless you need to shoot over 150 yds. While I do not care much for bolt action most Knights can be tuned up to shoot as good as any other muzzle loader and you already have one, I would be inclined to look very closely at bedding and mounting and recoil blocks and PM Sabot he knows a lot about Knights.
