Engineered for super-dense patterning with Hevi-13 loads, the wad-slowing Hevi-Shot Hevi-13 Turkey Choke Tube patterns tightly with lead and lead-alternative loads. A series of internal rings slow the wad, keeping it away from the shot cloud for extremely tight patterns. Axial porting reduces barrel jump.
