I shoot a TK2000. For grouse, 60 grains of 2f powder, usually Jim Shockey Gold, then a 2-3/4 plastic shot cup, an equal cup of #6 shot, then an over the shot card. I've knocked squirrels and grouse down with ease as some amazing distances with that tiny load. I use the JSG for grouse because on a day of hunting, I tend to shoot more then once. With JSG there is no swabbing. If any swabbing at all its the first three inches of the barrel. It cleans with water. I also have shot 3f JSG in the gun and my revolver and it work great. I just don't hunt in the rain with it.
For Turkey I shoot 80-90 grains of 2f (depending on the powder), a 3-1/4 plastic shot cup, and equal cup of #5&6 chilled shot mixed equal, and then two over the shot cards. This is a hard hitting, long range charge. With my decoys set at 25 yards, any Tom stupid enough to come in to that distance don't stand a chance. If they hover out at the 35 yard area, they still are dead bird.
