The PatternMaster Code Black Turkey Choke Tube is designed to deliver effective headshots on turkey at maximum shotgun range. Code Black tubes utilize PatternMaster's wad stripping technology, which produce extremely consistent patterns with short shot strings, by allowing the shot to exit the barrel before the wad. The tube's tight constriction, plus the wad stripping technology, results in extremely dense patterns that cover a turkey's neck and head at long range. Tubes extend out from the muzzle and have unique canoe porting that reduces muzzle jump, aiding the shooter for faster follow up shots. Patternmaster choke tubes are made of 17-4 stainless steel and are finished with a non-reflective bronze titanium coating. The PatternMaster Code Black Turkey Choke Tube is for use with ammunition designed for turkey hunting such as lead, copper and lead combination, and Hevi-Shot, as well as FLITECONTROL wads. (Not for use with shotgun slugs or steel shot.)
