Patternmaster 20ga CODE BLACK TURKEY combines constriction with our patented "wad-stripping" technology that increases down range energy for greater knock down power. Plus, the unique “canoe porting” reduces recoil so hunters are back on target faster and the porting allows the use of ammunition containing a “flight control” wad where normal “ported” tubes and barrels are not recommended. CODE BLACK TURKEY will extend out the end of your barrel one and a half inches and tubes have been designed with a three-step constriction for an expected Extra Full pattern and effective range between muzzle and 60 yards.  Recommended with ammunition designed for turkey hunting such as Lead, Copper and Lead combination, and Hevi-Shot.
CODE BLACK tubes are made from Carpenter Custom 630, aircraft quality, 17-4 Stainless Steel and have a Non-Reflective BRONZE Titanium coating.
Note: Testing done by Ballistics Performance has determined that ammunition with velocity of 1550fps and below will achieve the best results with Patternmaster Tubes.
