Ultra-Micro 4MM Full Metal Jacket and Carbon Injexion shafts have emerged as the top performers for archers seeking the highest level of arrow penetration. Reports from the field are compelling with bow hunters reporting dramatic improvement when downing big game.
4MM arrows focus their mass into a smaller diameter reducing surface area for less drag during flight and less friction through hide, flesh, and bone. “It penetrates deeper as the shaft passes through with less friction behind the broadhead channel,” said Gary Cornum, Marketing Manager for Easton. “Countless successful hunts testify to the awesome effectiveness of a simple concept that equates to more downed big game—it’s like magnum ammunition for your bow,” Cornum said. The small diameter also means that arrows fly much better in crosswinds than regular arrows, meaning broadheads will find the aim-point more often in the field.
