Every muzzle-loader is unique to itself and no gun is made exactly the same no matter how good the production practices a gun manufacture may have. My Knight rifle may like 110 grains and yours may like 120 grains or vice versa. Working up a "pet" load for a muzzle-loader is what every serious muzzle-loader hunter will have to do. I like to run a under-sized brush wrapped with a cleaning patch down the barrel several times after each shot to clean the barrel. I try to use a cleaning patch with Bore Butter. Do not clean the barrel between shots with cleaning jag. Using a cleaning jag will push any unburnt powder down the barrel and collect at the breech and will cause accuracy issues. Also, try to wait a few minutes between shots to allow the barrel to cool. It will take some time to find the pet load your Knight likes and may take more than one trip to the range to find the right load for your gun.
