The DDupleks Broadhead expanding slug line is designed for big game hunting. The concave ogive of the slug provides fast expansion and powerful shockwave. Broadhead slugs fragment after the hit providing a deep penetrating main body and 6 detached fragments that impact in a large area. This unique terminal ballistic design technology provides superior knock-down power for north american thin-skinned, medium game such as deer, javelina, bobcat, mountain lion, lynx, feral hogs and coyote.
