I own one and hunt with it. When loaded correctly, it is an easy 40 yard turkey gun. But grit your teeth because if kicks like a mule. And when I say kicks, I mean it. I am not normally recoil shy. But about ten turkey rounds out of my TK2000 and that is all I want to play with.
I shoot 100 grains of APP 2f and then a 3-1/4 shot cup.. one of the harder ones. I then fill an identical shot cut with a mix of #5 & # 7-1/2 shot. Pour that down the barrel. Then my foam over the shot cup to hold the mix together. I use the red primer jacket and a 209 Winchester Primer. My gun also has a red dot on it. Anything inside that red dot circle is done for.
The shotgun is a lot more friendly with the smaller wads for a 12 gauge. Squirrels I shoot 7-1/2 shot on 80 grains of APP 2f and that really knocks the tree rats. It is also my grouse load. I had a pine squirrel in the top of a tall popular tree and when I fired.. he flew out of that tree. He had to be 20+ yards up there.
The shotgun is as easy to clean as any of the other knight rifles with that open breech system. And since I shoot APP I do not have to swab between shots. They are well balanced and come to shoulder quite well. But they have a tight choke. I have an extra full choke for turkey and a modified for grouse. Both work real well.
But let me repeat.. you load that thing hard, and it kicks. I was shooting it one summer and it was T shirt weather. After about eight shots, I did not want to shoot. I was actually flinching.
