The Science of Shot is our way of saying that we are different. Patternmaster is the world’s only non-constrictive choke tube. Patternmaster is able to achieve substantially more energy on target through the continued development of our patented wad-stripping technology. Our most integral key to success is our stud ring. The exact placement of this stud ring within the tube stops the wad for a millisecond but allows the shot to continue without impediment. By stopping the wad, even for a split second, we are able to tighten the shot string as much as 80%. This enables our hunters to achieve mind-blowing accuracy and truly superior knock down power at distances most would think impossible.

The secret is the studs inside Patternmaster®. 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.

Our patented Stud Ring™ is in all Patternmaster Classic tubes and Code Black Duck, Goose, Upland, Decoy, Timber, and Big Games tubes.
