I've been using a Patternmaster for about 2 years (old style and new style - "wad wizard"). I shoot federal P156's with BBs at jackrabbits and sandhill cranes at long range (55+ yards) and kill both regularly. None of my friends kill them so effectively with their chokes/shells. I also use the wad wizard with P156's with #4B on coyotes, the combination is deadly! I patterned it against trulocks (which I do like, by the way), and the patternmaster outperformed them at long range. It was a bit too tight at closer range, which is why I also use the trulocks (mostly for quail and dove with 7.5 pellets).
