About Patternmaster

Patternmaster - the Science of ShotPatternmaster is the culmination of a single goal and three partners - Larry Leutenegger, a master gunsmith and machinist; Mike See, a hunting guide and farmer; and Jerry Poe, a purchasing agent and business manager. Approximately 20 years ago, as regulations were in place to ban lead shot from the marshlands, these three pioneers revolutionized the wing-shooting world with U.S. Patent #5,452,535 and Patternmaster was born. The idea was simple enough - create a more effective shotgun pattern to make steel shoot like lead - and they did it with a relatively simple but brilliant idea. The Science of Shot is what we like to call it.

About Our Tubes

How conventional chokes work:

Until the introduction of the Patternmaster tube in 1993, chokes used constriction as a way of controlling patterns. Constriction works just like a funnel, which does a good job of tightening the shot pattern. However, also like in a funnel, the shot cannot exit the barrel at the same time, which significantly lengthens the shot string, sometimes as much as 20 feet! (Shot String=distance from first BB to last as it exits the barrel)

As hunters, we rarely use a shotgun to hunt something that's not moving. A moving target combined with a long shot string makes it difficult to consistently muster enough pellets to knock down a target for a clean kill.

We are Different!

What makes the Patternmaster patent such an effective shotgun accessory for the hunter is the tighter shot string. A Patternmaster tube gives you a 2 to 3 foot shot string, compared to 15 to 20 feet from conventional tubes. The result is very simple; when you hit something you hit it with the maximum payload and energy. This means clean kills!

Patternmaster accomplishes this not by constriction but by the 5 studs cut out of the wall of our tubes. Where these studs are actually placed dictate the pattern each tube creates. Through about 20 years of research and develop we're pretty close to perfection. For a detailed explanation, see our videos located in our multimedia section.

Patternmaster Options

PATTERNMASTER "Classic" tubes: All "Classic" tubes are designed with Patternmaster's patented "stud" ring. Available in – 20ga, 12ga, 10ga Short Range (inside 40 yards), 20ga and 12ga Mid Range (20 to 50 yards), 20ga, 12ga, 10ga Long Range Ported in Black or Silver (30 to 60 yards), 20ga, 12ga, 10ga Long Range Unported Black only (30 to 60 yards), 12ga & 10ga Extended Range Ported in Black or Silver (30 to 70 yards), 12ga & 10ga Extended Range Black Unported (30 to 70 yards). Porting (holes around the outside of the choke) is a matter of personal preference. Porting helps to reduce some recoil but it will be louder to shoot, especially in a blind. Color is also up to the hunter, although, black is easier to conceal. Patternmaster "Classic" tubes are made from the finest 17-4 stainless steel and Heat Treated for maximum durability. Disclaimer for all Patternmaster "Classic" tubes: Warranty will not be honored if using Slug ammunition, or ammunition with a flight control wad used for in flight separation.

CODE BLACK tubes: To combat the endless question, "What tube should I use?" Patternmaster developed a line of tubes that are game specific. All CODE BLACK tubes are made from Carpenter Custom 630, 17-4 Air Craft Quality Stainless Steel and have a Bronze Non-Reflective Titanium Coating for corrosion resistance. CODE BLACK 12ga tubes are available in: UPLAND, PIGEON, TIMBER, and DECOY (These tubes are similar in performance to our "Classic" Short Range tubes), DUCK (Similar in performance to "Classic" Long Range), GOOSE and BIG GAME (Similar in performance to "Classic" Extended Range). All of the CODE BLACK tubes listed above follow the same warranty disclaimer as our "Classic" tubes. And then there is the CODE BLACK TURKEY! Our Turkey tube design combines the best of both worlds! It has constriction to tighten the pattern and a set of three rings spaced evenly throughout the tube to slow the wad. Unique porting allows for gas release and aids in the active release of flight control wads. This tube is safe to use with Lead or Non-Toxic shot. Disclaimer for CODE BLACK TURKEY: Warranty will not be honored if using Slug ammunition or Steel Shot.

BLACK CLOUD constriction tubes: As stated above, Patternmaster does not recommend ammunition with flight control wads to be used with our "Classic" and most CODE BLACK tubes due to the wad design. Flight control wads have plastic pedals that open and causes the wad to separate from the ammunition in flight. These pedals are a concern for Patternmaster due to the protruding studs inside most of our tubes. With that said, Patternmaster and Federal Ammunition worked closely together to create a tube to effectively master the Black Cloud ammunition. BLACK CLOUD tubes are available in 20ga, 12ga, 10ga FULL, MODIFIED, and IMPROVED CYLINDER constrictions. Patternmaster BLACK CLOUD tubes are made from the finest 17-4 Stainless Steel and are Heat Treated for maximum durability. Disclaimer for BLACK CLOUD tubes: Warranty will not be honored if using Slug ammunition.

ANACONDA GAS OVER CONSTRICTION TECHNOLOGY: There is a pattern to the Science of Patternmaster! Over and over we use properties within the ammunition to launch performance. Whether it is the wad restriction, the design of specialty tubes for ammunition, or making Steel shoot like lead, there are qualities within Patternmaster designs that are specific to ammunition properties. With ANACONDA, the same holds true! This time we are using the gas that is produce to assist in restricting the wad and control patterns. Inside ANACONDA tubes there is a patented "COIL ZONE" that is a precision-machined channel with a left twist to counter the natural right spin of the ammunition load. The channel fills with gas to surround and squeeze the wad to form consistent patterns. Due to the effort of the "COIL ZONE" there is no need to constrict the tube to smaller dimensions. Normal dimensions for a full constriction choke is 0.690. ANACONDA has proven to out preform the normal constriction choke with a constriction of 0.700. By opening the constriction, ANACONDA CS is able to reduce the pressure build that may be detrimental to the life of a shotgun. 12ga ANACONDA tubes are available in LONG RANGE 0.700 (0.715 Mossberg 835/935) effective range of 30-70 yards, MID RANGE 0.715 (0.730 for Mossberg 835/935) effective range of 20-50 yards, SHORT RANGE 0.730 (0.745 for Mossberg 835/935) effective range of 15-40 yards, and the STRIKER 0.670 Turkey (0.700 for Mossberg 835/935) tube for use with Lead or Non-Toxic Turkey loads. All Anaconda tubes are constructed from the finest 17-4 Stainless Steel and have the extended portion coated in a field grade OD Green color. Disclaimer for ANACONDA tubes: Warranty will not be honored if using Slug ammunition. STRIKER tubes are not to be used with Steel Shot.
