Gutpile, I have been shooting the Knight TK2000 for afew years now, and the load that work's best in my gun is:

100 grains Triple 7 fffg
overpowder wad
shot cup- 3"
2 oz. #5 shot
over shot wad

All gun's shoot differently, but you have the right equipment, so you should be able to dial in a good load. Good luck! If you need more info, post on this thread..................
