Sig Sauer Platinum Hunter 7mm Remington Magnum Ammo 160 Grain Nosler AccuBond Bonded Polymer Tip Box of 20

For elk, mule deer, and other hard-to-anchor game at extended range, 7mm Remington Magnum ammo delivers the flat trajectory and energy retention Western hunters count on. The Sig Sauer Platinum Hunter 160 Grain Nosler AccuBond Bonded Polymer Tip offers a factory load engineered around one of the most trusted bonded-core bullets in the hunting world — the Nosler AccuBond — which fuses a lead core to a gilding metal jacket for up to 60% weight retention after impact. Developed in partnership with the hunting experts at MeatEater, this 20-round box represents Sig Sauer’s flagship hunting offering, pairing precision powder charges with temperature-stable components and nickel-plated brass that resists corrosion in rain, snow, and humid timber.

Built for the Box

Each cartridge seats a 160-grain AccuBond polymer-tip bullet — Nosler’s signature bonded design that pairs the aerodynamic efficiency of a boat-tail with a white polymer tip that initiates expansion on impact while driving deep into vitals. The bonded core stays locked to the jacket through bone and heavy muscle, making it a favorite on bull elk at 300+ yards. Sig Sauer loads these rounds to 2940 fps muzzle velocity and 3070 ft-lbs of energy, giving you a 300-yard zero with minimal holdover out to 400. The nickel case provides slick extraction in hot chambers and reduces tarnish when rounds sit in a magazine for weeks at a time. Boxer primers and reloadable brass let you work up custom loads once you’ve shot the factory box. The G1 ballistic coefficient of 0.531 keeps the bullet supersonic well past 600 yards in standard atmospheric conditions, and the waterproofed primer seal ensures ignition in driving rain or condensation-heavy mornings.

Specs at a Glance

This load sits at the upper end of the 7mm Remington Magnum velocity spectrum for 160-grain bullets, making it a strong choice for shots beyond 250 yards where lesser loads begin to lose punch. If you’re shopping for 7mm Rem Mag ammo purpose-built for controlled expansion and deep penetration on heavy-boned game, the AccuBond bonded core delivers consistent mushrooming without fragmenting or separating from the jacket.

Who It’s For

Sig Sauer Platinum Hunter 160-grain loads are built for hunters who take elk, caribou, moose, black bear, and mule deer at distances where energy retention and wind drift matter. The 160-grain weight balances sectional density (enough to reach vitals through heavy shoulder bone) with velocity (flat enough for 400-yard shots without dialing elevation). If you shoot a rifle with a 24-inch barrel and a 1:9.5″ or faster twist, you’ll stabilize this bullet easily. Hunters running shorter barrels (22″ or less) will see velocity drop closer to 2850 fps, but terminal performance remains strong inside 350 yards. The nickel case is a practical feature for anyone hunting in wet climates or who keeps loaded rounds in a magazine for days — you won’t fight stuck brass or corroded primers when the shot opportunity finally arrives.

Care & Maintenance

Store ammunition in a cool, dry location away from heat sources and out of reach of unauthorized users. The waterproofed primers and sealed case mouths provide some moisture resistance, but long-term exposure to humidity can degrade powder over years. Rotate stock annually if you keep hunting loads staged in your rifle. Clean your rifle bore after every 40-60 rounds to remove copper fouling — the AccuBond bullet sheds less jacket material than some monolithics, but you’ll still see accuracy degrade past 0.5 MOA once copper buildup begins. If you reload, save the nickel brass separately from standard yellow brass; nickel cases require slightly different resizing force and can wear sizing dies faster if mixed carelessly.
