My Knight Disc is also an original. But I installed the Lehigh Conversion. This is a real good shooting load in the rifle. I also have a 2-7x32mm Nikon Pro Staff scope. This rifle is got a great trigger and the stock is very comfortable to shoot. I forget what Sabotloader told me this load would max out at, but I think this would make an excellent whitetail load.

IMO that is a great rifle you have there.
