The Nosler Trophy Grade 7mm Remington Magnum 160-grain load delivers controlled expansion and reliable weight retention across hunting distances. Nosler builds each round with the Partition bullet — a dual-core design that peels back the front jacket on impact while retaining more than half the original 160 grains for penetration through bone and vitae. At 2925 feet per second and 3040 foot-pounds of muzzle energy, this 7mm Remington Magnum ammo bridges the gap between open-country pronghorn shots and close-cover elk encounters. Nosler inspects each cartridge during hand-packaging, matching custom brass with consistent propellant charges and non-corrosive Boxer primers. For hunters who chamber magnum cartridges, this load eliminates the variable of fragmentation on shoulder shots and offers predictable terminal performance from 50 to 400 yards.

Performance at a Glance

The Partition’s design splits responsibilities: the tapered front section ruptures at the thin jacket mouth and curls uniformly outward, while the integral partition wall supports the mushroom and locks the rear lead-alloy core in place. The rear core — enclosed and crimped — resists deformation under the pressure spike of heavy magnums and drives through dense tissue. Nosler manufactures Trophy Grade ammunition in the United States, inspecting powder charges, seating depths, and case dimensions as part of their production protocol. Brass cases accept standard large-rifle primers and resize cleanly for handloaders who want to tailor velocity nodes or substitute projectiles after the initial factory load is expended.

Nosler’s Partition bullet has retained its dual-core architecture since 1948 — the front section handles expansion, the rear section drives penetration. You get predictable upset across a wide velocity window, from retained magnum velocities at 100 yards to impact speeds below 2200 fps at extended distances. This load suits hunters who need one cartridge for mule deer, elk, and black bear within a single season. Review current 7mm Rem Mag ammo inventory for additional grain weights and bullet styles.

Matching It to Your Build

The 160-grain Partition balances sectional density (0.283) with manageable recoil in standard-weight hunting rifles. Barrel twist rates of 1:9.5 or faster stabilize this bullet length across temperature extremes. Zero at 200 yards places the first drop below 3 inches near 250 yards, keeping holdover within one MOA for most field conditions. The Boxer primer and reloadable brass extend the value of each case — resize, trim to 2.500 inches, seat a fresh 160-grain projectile over 60-65 grains of appropriate powder, and you replicate factory ballistics at the loading bench.
