Excalibur has done years of research and found that down range velocities and penetration greatly declined with lighter weight broadheads. That is why they introduced the Boltcutter to deliver the accuracy and down range energy essential for success in crossbow hunting. This broadhead increases the front of center balance of your crossbow bolt delivering deeper penetration while maintaining the superior accuracy needed to successfully harvest big game. Made from high strength stainless steel, this broadhead is one of the most durable broadheads available.
