<font color="red"> The MATCH VLD bullets are proving to be the most lethal big game hunting bullet available. The VLD design incorporates a sharp nose that allows the bullet to penetrate up to 3 inches before it starts to expand. This delayed expansion results in a wound channel that is deep inside the vital area of any big game. After the bullet starts to expand it will shed 80% to 90% of its weight into the surrounding tissue traveling as deep as 18 inches. This results in a massive wound cavity that creates the greatest possible amount of tissue damage and hemraging. This massive and extensive wound cavity result in the animal dropping fast. Our bullets don't poke through like an arrow but instead expend all of their energy right where it is most effective, inside the animal. Bullets that poke through so that they can cause a blood trail result in a hunter tracking a wounded animal. Using the Berger VLD will result in an animal that goes down fast so you can enjoy the results of your hunt without having to track the wounded animal after the shot. You owe it to yourself to see how accurate and deadly the Berger VLD will be on your next hunt. Call 714-447-5456 to request video proof of these results in the field.
