I had a Knight TK-2000 and it was a very accurate & great patterning shotgun. But the Knight stock design & my shoulder are not a match! That thing hurt me every time I pulled the trigger! I tried up to 120 grains T-7 in it, and anything over a 100 grains will definately get your attention! Patterns started to "blow" after 110 grains, but 100 grains provided the best pattern. Sold it to a buddy who it fits much better.
