corey.. I enhanced your picture for you so your hits show up a little better. That XTP looks like it is doing a pretty good job there. Did you shoot more of them? Were you swabbing between shots?
I have a Knight LK-II which is a lot like your Knight USA. The LK-II is considered the Wolverine I was told. If you ever see any of them in a store, pick up a pack of Saber tooth Conicals and try them with 90 grains of powder. My little Wolverine and my Disc both really liked them in the 250 & 300 grain weights. The 300 grain and the Knight Disc had a real thing going actually. They are cheaper then powerbelts. My LK-II did not like powerbelts.
