Nosler Trophy Grade .300 Winchester Magnum 200gr Partition ammunition is a box of 20 rounds (Nosler part no. 60069) loaded with a 200-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 elk and moose-sized game, which makes it a natural fit for a .300 Winchester Magnum rifle on a big-game hunt. Nosler publishes a muzzle velocity of 2750 fps for it, measured in a 24-inch test barrel.
