Successful turkey hunting requires the ability to send a dense, lethal pattern of shot at ranges up to 40 yards or more. The Primos Jelly Head Maximum turkey choke has an extended taper to tighten patterns and fluted ports for recoil reduction. The choke tube is designed to achieve a 90 percent pattern density at 40 yards. The Jelly Head is compatible with Hevi-Shot copper plated or regular lead shot.
