The Sako Powerhead Blade .308 Winchester 162-grain load is engineered for hunters who need pinpoint accuracy and absolute bullet integrity on medium-to-large big game. The biggest headache with traditional monolithic solid copper bullets is that they can fail to open up if they lose too much velocity downrange, or they can pancake and stall out when hitting heavy bone at close range. Sako completely eliminates this flaw by using a specialized polymer-driven expansion system and a staged internal cavity that forces the bullet to expand perfectly at any distance.
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 mechanical plunger on impact, forcing hydraulic pressure into a deep reaction chamber. This initiates immediate expansion, while a unique 5-stage internal bullet geometry meters that expansion to a precise limit—ensuring the bullet mushrooms uniformly without shearing its petals or losing its weight.
Leaving the muzzle at 2,674 FPS with a 0.390 G1 ballistic coefficient, this 162-grain powerhouse holds onto its speed to deliver devastating kinetic energy far downrange. Because the solid copper body refuses to separate or break apart under intense rotational forces, it retains 100% of its weight. This massive structural mass drives the expanded bullet straight and deep through thick hide, heavy muscle tissue, and dense shoulder bone for a quick, clean, and ethical harvest.
Key Benefits
- Oxygen-Free Solid Copper: Premium monolithic construction entirely eliminates core-jacket separation for 100% weight retention.
- 5-Stage Blade Expansion: Advanced internal geometry controls mushrooming perfectly across a massive velocity window, preventing over-expansion.
- Hydraulic Polymer Tip: The green Blade tip drives backward into a specialized reaction chamber to kick-start expansion, even at extended ranges.
- Sako Match-Grade Precision: Built to Sako’s legendary European manufacturing standards for strict velocity consistency and sub-MOA field accuracy.
