I'm just one step ahead of you Snook. These other guys know a lot more about the art and science of black powder shooting than I do. I just got into shooting a muzzleloader last March. I got a Knight KRB7 and have been very pleased with it. The gun was easy for me to learn to operate and I like the ease of takedown for cleaning. I'm going after elk in Colorado this fall so my choice of shooting components has been with that in mind. I've tried both platinum powerbelts and Hornady Great Plains Conicals. They both shoot very accurately with the looseffg 777 powder. I haven't tried other BP's. I will say that 120 grains behind a 338 gr. powerbelt will kick the snot out of you.The 80 gr. load behind the Great Plains is much more pleasant to shoot.
I've noticed the same thing others have mentioned about the high comb of the KRB stock. I can get down on the sights, but I have a thin face and I have to move forward on the stock to do it. I like the sights themselves. I like them much better than my buddy's Omega. They are fairly fine sightsand are easy to shoot accurately,even with my aging eyes.If you are planning to scope the gun, this may not be a factor for you.
