Then, the new ultra-micro 6-40 “Deep Six” thread standard was introduced, opening up performance levels to hunters that were previously the exclusive territory of tournament archers. This offered hunters the ultimate in friction reduction for higher velocity downrange and more penetration passing through the target. With a more lethal system now available to hunters, Deep Six arrows and broadheads are showing their worth in the field. The results have proven so effective that more companies are introducing 4MM arrows and Deep Six broadheads designed for the new micro standard. Ultra-micro diameter 4MM FMJ and Carbon Injexion arrows are a prime example of the Deep Six technology in action. For the hunting archer, Deep Six broadhead-tipped 4MM arrows provide more penetration by concentrating the mass of the arrow into a smaller column. Bowhunters using Deep Six are regularly reporting complete pass-throughs, improved blood trails, and quicker game recovery.
