If you shoot the right loads determined by patterning through the PatternMaster, you should get some good performance. As you probably know, the PM is a wad-stopping choke which shortens the shot string creating a more dense pattern. It is designed to work with bigger pellets though, like BB's and BBB's.
One thing I disliked about mine was the porting. Shooting out of a Pit Blind, it was deafening for those in the hole and the dog if he was close by. I have since removed my dog from the equation by sending him down the check about 30-35 yards where he can see the entire playing field. Much safer for him.
