Nosler Trophy Grade .300 Remington Ultra Magnum 165gr Partition ammunition is a box of 20 rounds (Nosler part no. 60064) loaded with a 165-grain Spitzer Partition bullet in Nosler Premium Brass. The Partition is the bullet Nosler calls the benchmark for hunting bullets since 1948, and its dual-core design lets the front core expand rapidly while the integral partition supports the mushroom and keeps the rear core intact for deep penetration. Nosler classifies this load for deer-sized game, which makes it a natural fit for a .300 Remington Ultra Magnum rifle on a big-game hunt. Nosler publishes a muzzle velocity of 3350 fps for it, measured in a 24-inch test barrel.
