12ga Benelli Sport/Beretta Optima Code Black Turkey .665
 
The Patternmaster Code Black Turkey uses a number of different technologies to achieve incredible down range energy at distance. We’ve worked hard to continue to develop a “hunting” pattern that performs like no other. We understand that sometimes your entire season can come down to a few more yards.
The Code Black Turkey is built from titanium infused 17-4 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.
The Code Black Turkey technology uses a three-phase step down constriction to .665 as well as our proprietary canoe-porting... this combination of technologies shortens the shot-string by as much as 75% over constriction tubes.
*Ballistic Specialities recommends ammunition speeds below 1550 FPS for best results..
