The launch of our homepage! The Hard-Hitting Shooting Lab. This page will be full of rifle bullet tests in the future! We want to welcome you to our page with the article of a really interesting product. Sako Oy’s brand new lead-free hunting bullet! The Sako Powerhead Blade!
At saturday we had a “Sako Shooting Day” at the Hard-Hitting Shooting Lab! Maybe we did a first ever Sako Powerhead Blade bullet test? In the Finland? In the world?
Before we go to the test results, we want to give our big thanks to Sako Oy, who handed these brand new Sako cartridges for us to test! Really great gesture for the enthusiasts, because there are a lot of people who are interested how this new lead-free hunting bullet will perform. It also shows their trust towards their own products when they give it to us to test!
I would like to say that it was really courageous act from them!
But, to the results!
Ladies & Gentleman! The Sako Powerhead Blade, 308win, with the 162gr bullet!
The factory load! The first time ever I see a lead-free hunting bullet to open over 18mm width in 308win! The bullet opened all-the-way to the bottom of the expansion cavity with the impact speed of 792m/s. I would say, that this Sako Powerhead Blade 162gr bullet is optimized for the velocities of the 308win! Velocity of this factory cartridge is spot on for this bullet and that is great thing when thinking about the future users of this cartridge. Notice that the 30-06spr and 300wm cartridges they released together with this 308win version, have a different bullet, which probably is developed for the higher velocities!
The reloading of the new bullet! I probably would not add much more velocity for this new Powerhead Blade 162gr bullet, because I think it is not planned for the higher velocities than the factory cartridge has. Of course, you seldom have a possibility to shoot a moose with your barrel touching the side of it, so you can adjust your desired impact speed for the specific distance by reloading.
The specification of the cartridge promises the velocity of the bullet to be an 815m/s at the muzzle. We shot these tests with the Tikka T3x Tactical which have a 600mm barrel and the velocities were as promised. If the bullet leaves the barrel with the velocity of 815m/s the flying velocity of the bullet is about 646m/s at the distance of 225 meters. Expansion of the bullet at that distance is also very good.
Test targets were wetted newspapers. The bullet with impact speed of 792m/s penetrated 46cm of wet newspapers and the bullet with impact speed of 646m/s penetrated 58cm. Considering the very good expansion of the bullet, these penetrations are also very good.
The wound cavity. Sako has told on their marketing material, that they have developed this bullet to open fast and really reliable. That is also the reason, why they used a pure copper instead of a gilding or copper alloys on this bullet. The fast opening could also be seen on our test. The wound cavity and the bullet opened really fast and it was easy to see immediately after shot on the external surface of the newspaper pile. The cavity opened really quick from the surface to the width of 5cm. Then widening fast to 10cm width and even from there to 14cm width. After that the cavity started to reduce.
Summa summarum. This is a lead-free hunting cartridge loaded with a bullet, that is made for this cartridge. You can expect really good performance!
Thrilled? – Yes, we are! Cannot wait the other Sako Blade bullets & cartridges to hit the shelves!
