Nosler Ballistic Tip® Varmint bullets thrive on ultra-high velocity loads. Nestled in the jacket mouth is the streamlined polycarbonate tip, color-coded by caliber. The Ballistic Tip® Varmint's ultra thin jacket mouth assures violent expansion at either end of the velocity scale. The uniform, gradual thickening of the jacket wall at the bullet's mid-section is designed to keep the Ballistic Tip® Varmint together until impact ­ at any velocity. The heavy jacket base prevents bullet deformation during firing. Nosler's unique Solid Base® boat tail design, combined with the polycarbonate tip, dramatically increases long range ballistic efficiency. This is not loaded ammunition.
