Buy Berger Hunting Bullets 284 Caliber, 7mm (284 Diameter) 140 Grain VLD Hollow Point Boat Tail. The Berger Hunting bullet line features  match grade bullets that have the highest possible ballistic coefficient designed for 300 yards or more. Berger recommends that the bullets be seated to touch the rifling for best accuracy. Note, however, that the resulting cartridge overall length may be too long for some magazines. The VLD design incorporates a sharp nose that allows the bullet to penetrate 2″ to 3″ before it starts to expand. After the initial expansion, the bullet will shed between 40% and 85% of its weight as shrapnel into the surrounding tissue (internal organs). The combination between the shrapnel and the hydrostatic shock produces a massive wound cavity within the vital area that will be 13″ – 15″ long. This is not loaded ammunition.
