The secret is the patented studs inside Patternmaster choke tube! They slow the wad for a fraction of a second and as it pauses the shot charge leaves the barrel undisturbed by the wad and gasses. By taking the wad and gasses out of the equation, Patternmaster delivers beautiful, even, dense patterns with all loads and shot sizes.
The patented "Stud Ring" is in all Patternmaster Classic choke tubes and Code Black choke tubes.
