Nosler Trophy Grade .300 Winchester Magnum 200 Gr. Partition- Box of 20

The Nosler ballistics team, long respected in the hunting and shooting industry for reliable and precise reloading data, is the driving force behind Nosler Trophy Grade Ammunition. Trophy Grade Ammunition brings Nosler’s unsurpassed quality standards in accuracy and consistency directly to the shelf of your favorite gunshop or outdoor retailer.

Partition Bullets feature a fully tapered jacket that ruptures instantly at the thin jacket mouth, yet the gradual thickening along the bullet’s axis controls expansion and curls the jacket uniformly outward at high or low velocities. Nosler’s integral partition supports the expanded mushroom and retains the rear lead alloy core. The enclosed rear core retains more than half the original bullet weight for deep penetration. The special crimp locks in the rear core section, adding strength to resist deformation under the pressure of heavy magnums.

This ammunition is new production, non-corrosive, in boxer-primed, reloadable brass cases.
