I have a couple Patternmaster tubes that I swear by for waterfowl. Maybe it is hocus pocus but I shoot better with them in the gun. As someone stated above, be careful with a standard Patternmaster when shooting a shell with a flight control wad. They say it can blow up the end of the barrel. The folks at Mack's Prarie Wings,in Stuttgart, say they have seen guns come in with barrels that were blown out from doing this.
