S20 Cold hammer forged barrel

Cold hammer forged barrel

All Sako rifles, including the Sako S20, feature match-grade cold hammer forged barrels. There are many advantages to cold hammer forged (CHF) barrels: they’re durable, accurate and have excellent tolerances. The cold hammer forging technique changes the structure of the steel, increasing its toughness and making the barrel life of your rifle longer. CHF barrels do not have to be broken in, but instead have superb out-of-the-box accuracy.  

DURABILITY

Cold hammer forged barrels have improved resistance to erosion caused by heat and pressure.

SUB MOA ACCURACY

The smooth bore surface ensures less resistance on the projectile. We also inspect every single barrel’s straightness, surface smoothness and consistency by hand in order to guarantee sub MOA accuracy.

HIGH TOLERANCES

Thanks to consistently superb rifle tolerances of cold hammer forged barrels, Sako is one of the top rifle barrel manufacturers.

More accuracy with Cold hammer forged barrels

At Sako, our specially trained professionals manually check every single barrel as no automated device can replace the human eye to inspect the barrel straightness, perfect rifle consistency and surface smoothness. What’s more, every rifle is tested by hand to guarantee sub MOA accuracy.

Are cold hammer forged barrels better?

Sub MOA bolt action rifles, such as Sako S20, provide extreme accuracy 
both on the range and in the wilderness. 

MOA accuracy refers to the accuracy and consistency of the rifle. ‘MOA’ refers to Minute of Angle and means the rifle’s capability to constantly deliver a grouping of shots from a certain distance. So, sub MOA accuracy means that at 100 yards, Sako S20’s five shots would all lie under one inch apart. 
In other words, repeatable accuracy is guaranteed. 

What is a CHF barrel?

The cold hammer forging begins with deep hole drilling and carefully honing the barrel for a supreme interior finish with immaculate roundness and diameter consistency. Then, the barrel is hammered from all sides against a mandrel placed inside the barrel, transferring the reverse image of the rifling machined on the surface of the mandrel. This reduces the outside diameter without removing material and increases the tensile strength of the barrel. Hammer forging, together with annealing, removes distortions and leaves a smooth bore surface with superior rifling quality. This offers less resistance on the projectile and ensures better barrel longevity than other manufacturing processes.

What is sub MOA accuracy?

Sub MOA bolt action rifles, such as Sako S20, provide extreme accuracy both on the range and in the wilderness. MOA accuracy refers to the accuracy and consistency of the rifle. ‘MOA’ refers to Minute of Angle and means the rifle’s capability to constantly deliver a grouping of shots from a certain distance. So, sub MOA accuracy means that at 100 yards, Sako S20’s five shots would all lie under one inch apart. In other words, repeatable accuracy is guaranteed. We also recommend using Sako Cartridges as all Sako rifles and cartridges are tested to guarantee 1 MOA or better accuracy straight out of the box.
