The lead free choice for silencers and short barrels
ECOSTRIKE™ brings the latest in bullet technology into a lead-free projectile. Our copper bullet delivers deep penetration, almost 100% weight retention and a high BC. To make the bullet lighter and prevent it from fragmenting, the lead has been replaced by copper and nickel.
ECOSTRIKE™ is the lead-free choice for hunting medium and large game due to its excellent ability to expand at both low and high velocities.
The Ecostrike Silencer cartridge is loaded with our popular lead free Ecostrike bullet in our dark grey cases that also helps you to keep your standard loads and Norma Silencer Series separated when the bullets are the same.
The features of the Ecostrike bullet are the same as on our standard ammunition but the load is optimized for shorter barrels, 50 cm instead of CIP standard 61 cm. If you have a shorter barrel than 61 cm, you benefit from shooting Norma Silencer Series even without a silencer/suppressor. With an optimized load, you get greater speed and more effect, closer to your standard ammunition shot in standard 61 cm barrel.

About the caliber
This is the sporting version of 7,62x51mm NATO. It was introduced by Winchester in 1952 - only a year after the new NATO cartridge. As most other military cartridges it was expected to become popular for hunting quickly and Winchester wisely decided to make a civilian version with their name.
The purpose of the new military design was to make a more compact cartridge with a quicker cycle rate than the .30-06, and enabling a soldier to carry more rounds. It also has excellent accuracy potential and is favored by many target shooters. As the .308 Winchester fits into short bolt actions and delivers almost the same energy as the .30-06 with medium weight bullets it has become one of the most popular cartridges in the world.
The case capacity is not suited to bullets much heavier than 180 grains, however, and accordingly some hunters finds it too light for the largest species like the big bears. It is important to know that the .308 Winchester is not entirely identical to the 7,62 NATO in all dimensions due to differences in tolerances, and some rifle chambers cannot handle military ammunition.
