Sako Gamehead Varmint RX – 308win Factory cartridge – Bullet test

At april we had a “Sako Shooting Day” at the Hard-Hitting Shooting Lab! We tested the Sako Gamehead Varmint RX 308win factory cartridge at the same day, when we tested the new Sako Powerhead Blade 308win cartridge. Sako Powerhead Blade test you can find here -> LINK

Before we go to the test results, we still 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 intersted about these new Sako cartridges!

But, to the results!

Sako Gamehead Varmint RX 308win cartridge with 130gr varmint bullet!


Tests were shot with the Tikka T3x Tactical rifle with the 600mm barrel. We measured the velocity ca. 5m from the muzzle and got a 942m/s (3090fps) impact velocity. Manufacturer promises the velocity of 940m/s (3084fps) at the muzzle, so it was spot on!


The optimal working style of the varmint bullet is to explode to pieces! This Sako Gamehead Varmint RX, is the hollow point, boat tail bullet for the varmints! Developed by Sako Oy. With the weight of 130gr it is little heavier than the other manufacturer’s varmint bullets in 308win. Maybe it will have same kind of trajectory than the normal hunting bullets, because of the weight? The possibility to use also the varmint bullet without the need of re-adjusting the rifle scope? I do not have answer to that yet, but I am eager to see it.

First target was 70cm of wetted newspapers and after that a 5-liter water jug. Our idea was to secure also the end part of the bullet, if the bullet would not explode completely. I can tell, the first shot was a blast! The water jug fell off the table, though it was on the other end of it! There was a huge crater emerged on the newspaper pile! The hole on the external surface of the paper, was almost 10cm (3,9″) wide! After our laugh little settled down, we noticed that there is a huge wound cavity inside the newspapers! It was 24cm (9,4″) deep and it was getting even wider inside. We measured the width of the cavity to be a 16-17cm (6,5″) wide inside of the crater!

Below you can see the wound channel of the Gamehead Varmint RX.

Second target was 5-liter water jugs. Those exploded one after another. Yes, we could not stop after the first one. It was a great joy! =D What we noticed, was that if the backside of the water jug did not rip apart, there still were no exit holes of the bullet at the back wall of the jug. The bullets were completely exploded before the back wall. I would say that Sako Gamehead Varmint RX bullets works as good varmint bullets should work… they explode!

At the moment, this bullet is only available in factory cartridges.


The Sako Gamehead Varmint RX bullet exploded almost completely, as you can see on the photos above. It is a true varmint bullet. When you are shooting a fox with the Gamehead Varmint RX the skin of that fox will be a quite tight at the short period of time! It would not take a single step after the impact. I am sure of it!

PS. This Sako Gamehead Varmint RX will also be available in 30-06spr caliber, which is really great, because the selection of 30-06 varmint cartridges in Finland, is completely zero at the moment. The velocity of the 30-06 is adverticed to be 975m/s (3199fps).
