Shop 7mm Remington Magnum ammo from Nosler — the Custom line brings hand-assembled precision to a magnum hunting cartridge built for elk, moose, and bear at extended range. Each 175-grain Nosler Partition bullet exits at 2800 fps and delivers 3046 ft-lbs at the muzzle. The Partition’s dual-core design maintains 60-70% weight retention through shoulder bone and heavy tissue, driving straight-line penetration while expanding predictably. Nosler ballisticians hand-throw each powder charge, seat primers individually, and verify concentricity before the round goes in the box. You get the consistency of handloads without the press time. Brass is cut to SAAMI spec, flash holes inspected, chamfered and deburred. Boxer primer seats allow full reloading after firing. For hunters stepping into magnum-class cartridges or precision handloaders verifying their own recipes against factory baselines, this is the reference load.
Load Profile
The 175-grain Partition sits in the middle of the 7mm Rem Mag’s useful range — heavy enough for large-bodied game, light enough to stay supersonic past 600 yards. Nosler’s G1 BC of 0.519 and sectional density of 0.31 balance wind deflection against terminal momentum. At 300 yards, velocity holds near 2400 fps with over 2200 ft-lbs remaining. The jacketed soft point nose initiates expansion on impact, while the partition wall retains the rear core for penetration. New brass from popular reloading brands (Nosler when available) means uniform neck tension and consistent chamber fit. Corrosive-free Boxer primers fire reliably in temperature extremes. Each round is hand-packaged in plastic ammo boxes with ballistic data printed on the label — no guessing drop or drift at distance.
