Patternmaster CODE BLACK BIG GAME tubes will extend out the end of your barrel 1 1/2 inches and has an effective range of 70 to 80 yards. The difference between the Patternmaster CODE BLACK BIG GAME and Patternmaster CODE BLACK GOOSE is the ported through holes. Use the BIG GAME tube when porting is not the best choice. For instance, in a duck blind, or when using large lead shot such as 00 & 000 Buck. You will see a patterns similar to a Full constriction choke on paper with a 2 ¾” 3’ and 3 ½” shell, but because of the patented "stud ring" inside the tube, there is a much shorter shot string. This shorter shot string will allow more shot on target all at once so your down range energy is sure to kill instead of cripple. This tube is a favorite for Coyote and Deer hunting (where Buck shot is allowed). Pick your favorite shot size to use which can range from 8 to BB Non-Toxic/Steel and Lead 8 to 000 Buck. CODE BLACK BIG GAME tubes only come in a Non-Reflective Bronze titanium coating and are not ported. All Patternmaster tubes are made of Carpenter Custom 630 (aircraft quality) 17-4ph stainless steel and are heat treated to the optimum level for best performance.
Note: Testing done by Ballistics Performance has determined that ammunition with velocity of 1550fps and below will achieve the best results with Patternmaster Tubes.
This tube should not be used with slug ammunition or ammunition with a “Flight Control” wad.
