The Sako Powerhead Blade 7mm Remington Magnum 140-grain load is custom-engineered for big-game hunters who demand flat-shooting magnum performance paired with absolute bullet integrity. The classic flaw with traditional solid copper bullets is that they can fail to open up if they lose too much velocity downrange at extended distances. Sako completely eliminates this vulnerability by using a specialized polymer-driven expansion system that forces the bullet to mushroom perfectly, whether you are taking a close-range brush shot or reaching across a wide-open canyon.
The technical advantage lies in managing expansion kinetics within a pure, homogeneous copper projectile. Rather than standard commercial copper, Sako uses 100% premium, oxygen-free copper that is highly ductile and completely resists fragmentation. Up front, the signature green Blade polymer tip acts as a physical initiator. On impact, it drives backward to force radial expansion inside a deep reaction chamber—meaning it doesn't rely solely on hydraulic pressure like traditional hollow points. A unique 5-stage internal bullet geometry then meters that expansion to a precise limit, ensuring the bullet holds together perfectly.
Screaming out of the muzzle at a blistering 3,084 FPS with a sleek 0.362 G1 ballistic coefficient, this 140-grain powerhouse delivers exceptional energy retention downrange and masterfully resists crosswind drift. Because the solid copper body refuses to separate or break apart under intense magnum forces, it retains 100% of its weight. This massive structural mass drives the expanded bullet straight and deep through thick hide, dense muscle tissue, and heavy shoulder bone for a quick, clean, and ethical harvest.
