The 12ga Patternmaster Code Black Turkey (0.665) uses several different technologies to achieve incredible down range energy at distance. We've worked hard to continue to develop a Turkey pattern that performs like no other. We understand that sometimes your entire season can come down to a few more yards and that's why The Patternmaster Code Black Turkey uses our Separating Ring technology as well as our proprietary canoe-porting in order to shorten the shot-string by as much as 75% over other constriction tubes while also improving the effective range. The Code Black Turkey is built from titanium infused 17-4ph Stainless Steel and more than 100 years of combined experience. This American Made, aircraft quality steel is the best in the world and allows for unmatched performance and durability.
