Nosler Ballistic Tip Hunting 7mm .284 140 GR Spitzer 50 Box. 284 140 GR Spitzer 50 Box - Nosler engineered the Ballistic Tip Hunting bullet to be very predictable and extremely forgiving. The polymer tip resists deformation in the magazine initiates expansion upon impact and is color-coded by caliber. The fully tapered jacket and special lead alloy core allows controlled expansion and optimum weight retention at all practical velocity levels. A heavy jacket base prevents bullet deformation during firing and acts as a platform for large diameter mushroom. Nosler's unique solid base boat-tail design combined with the polycarbonate tip dramatically increases long-range ballistic efficiency.
