WhenI shoot them in my Knight Disc I use 120 grains of Goex 2f or Pyrodex RS and the accuracy is exceptional.

Out of my Thompson Center Black Diamond XR I shoot them with 110 graind of Triple Se7en (loose) or two Pyrodex Pellets.

Out of my Knight Wolverine LK-II I shoot them with 100 grains of Goex 3f.

I've never shot them out of the other inlines. The Knight Disc with open sights really impressed me with accuracy the first timeI shot them out of the rifle..
