Sako Powerhead Blade 645A is a lead-free .308 Win hunting cartridge with a 9.7-gram (150-grain) monolithic copper bullet.
Sako Powerhead Blade 645A is a lead-free .308 Win hunting cartridge with a 9.7-gram (150-grain) monolithic copper bullet. With an initial velocity of 840 m/s, a ballistic coefficient of 0.401, and high weight retention, it offers an excellent combination of flat trajectory, controlled expansion, and penetration. Suitable for use in Lead-free hunting Hunting medium and large game Ambush and stalking hunts Open and mixed terrain .308 Win hunting rifles When good penetration is preferred To reduce meat contamination Why choose Powerhead Blade 645A? 9.7 g / 150 gr copper bullet Lead-free monolithic construction Initial velocity 840 m/s Ballistic coefficient 0.401 High weight retention Controlled expansion Low risk of fragmentation Good penetration 20 cartridges per box Technical data Manufacturer: Sako Series: Powerhead Blade Caliber: .308 Winchester Bullet code: 645A Bullet weight: 9.7 g / 150 gr Bullet material: copper Bullet type: lead-free monolithic bullet Initial velocity: 840 m/s Ballistic coefficient: 0.401 Box contains: 20 cartridges Country of manufacture: Finland Set includes 20 × Sako Powerhead Blade .308 Win 9.7 g cartridges Frequently Asked Questions Does the cartridge contain lead? No. Blade is a monolithic copper bullet. How does the 9.7 g Blade differ from the 10.5 g version? The 9.7 g model is lighter and has an initial velocity of 840 m/s. The 10.5 g bullet is heavier, slower, and may offer greater impulse mass and deeper penetration. Does the copper bullet hit the same point as a lead bullet? Not necessarily. Differences in bullet length, shape, and barrel friction can change the point of impact. When is the Blade 645A the right choice? This variant is suitable for hunters who want a relatively light, lead-free .308 Win bullet with a good ballistic coefficient. For heavier game or shorter distances, the 10.5 g Blade may be a better choice. Recommendations Clean the barrel before switching from a lead-core bullet to a monolithic copper bullet and check accuracy with a group of shots. A copper bullet of the same weight is generally longer than a lead bullet and may interact differently with the rifling. Check the point of impact even if you have previously used Gamehead or Super Hammerhead of the same weight. When hunting, consider the bullet’s good penetration and ensure a suitable backstop and safe bullet trap. Lead-free 150 gr hunting cartridge Sako Powerhead Blade 645A combines a 150 gr copper bullet, 840 m/s initial velocity, and a ballistic coefficient of 0.401.
