308 WINCHESTER HPBT MATCH X 20 q RECREATIONAL SHOOTING AMMUNITION

Restrictions on use

Use only in firearms of the corresponding calibre.

Always make sure before firing that the barrel is not obstructed.

THIS AMMUNITION IS BANNED FOR HUNTING

Muzzle velocity by barrel length

The muzzle velocity of ammunition depends very much on the length of the gun’s barrel, so we have performed tests using different barrel lengths in order to best characterise these speed variations. Warning: there may be differences in velocity from one barrel to another with the same length



20-inch (51 cm) barrel: 760 m/s

24-inch (61 cm) barrel: 800 m/s

26-inch (66 cm) barrel: 810 m/s

Quality-controlled and regulated

This match ammunition is controlled in the factory, and we control the muzzle velocities, pressures, dimensions and also accuracy. The weapon used is a barrel held in a vice, and a control is performed on the start, middle and end of the product batch by firing a round of 20 shots. The 20 shots are fired as four groupings of five bullets and the 100 m grouping must be less than one MOA (29 mm). If a grouping is above this value then the batch is rejected.

Ballistic coefficient explained

The ballistic coefficient is a numerical value that characterises the ability of a projectile to maintain its speed, and therefore energy, over a distance. The higher the value, the greater the range of the projectile. Coupling this with the speed of the projectile allows you to configure your ballistic calculator to predict the trajectory of the bullet. Please note: as the type of gun has a major impact, you may notice differences in relation to the data provided.
