For western hunters pushing shots past 400 yards on elk and mule deer, 28 Nosler ammo delivers the velocity and energy needed to anchor game at distance. The Nosler Trophy Grade load chambers a 160-grain Nosler Partition — a bonded dual-core bullet engineered to mushroom predictably at high velocity while retaining mass for deep penetration. With a G1 ballistic coefficient of 0.475 and sectional density of 0.283, this round holds energy downrange and bucks wind better than most standard hunting bullets in the same weight class. Nosler manufactures Trophy Grade ammunition to match-grade tolerances, hand-inspecting each cartridge before boxing. Brass cases are Nosler Custom stock — uniform wall thickness, boxer-primed, reloadable. If you’re stacking handloads for precision or need factory ammo you can trust when a bull steps out at last light, this is the round that shows up.
Performance at a Glance
The Partition’s dual-core design separates into front and rear sections at the mid-body partition wall. On impact, the thin front jacket mouth ruptures and peels back in controlled fashion, creating a wide wound channel. The partition prevents the rear core from fragmenting — that enclosed lead alloy retains more than half the bullet’s original weight and punches through shoulder bone, heavy muscle, and hide without keyholing or tumbling. The tapered jacket curls uniformly outward regardless of impact velocity, so performance stays consistent whether you’re shooting at 200 yards or 600. Nosler crimps the rear core section into place, adding structural integrity under magnum chamber pressures and preventing core separation during flight or on impact.
