Core principle

The core principle of the FIER Ammunition projectiles is the one of a bipartite, sub-calibrated and double effect projectile, placed in a plastic container, that is itself locked by a pressure regulator. Its specificity, for a sub-calibrated projectile, is to remain as a single compact projectile along its trajectory. There is no separation at the end of the barrel. The release of the internal bipartite projectile only occurs at impact. This principle and this specificity provide high qualities to the projectile, including a double-effect. This effect, which ensures a better penetration in the target, is due to the composition of the internal projectile released during impact made of an arrow (element of penetration) and a hammer. These two elements will act together or individually according to the type of target reached. The shapes and materials of those two elements will offer multiple action benefits during impact. In 20 gauge the projectile is of single effect composed of a unique arrow-hammer.

Features

MORE SAFETY

By remaining compact on its trajectory.

• with its head shape that makes it fall to a maximum range of 150/200 metres (for horizontal shot, shoulder-fired shot, level surface shot).
• with the significant reduction of ricochets, according to the tip of the arrow, to the shape of the container, to its grooves, allowing to hook the target even for a tangential shot.
  

A very good precision

• Thanks to the special shape of the container
  
• Thanks to the combination of a heavy central mass, and a light outer casing.
  
• Thanks to a high and regular speed.
  
• Thanks to the automatic adjustment at the boring of the barrel, which provides a good precision in all barrel chokes.
  

The FIER Ammunition bullet is composed of the following parts (except 20 gauge and MSTDF) : : a container, a central arrow, a hammer and a pressure regulator. The container and the pressure regulator are in plastic, the arrows and the hammer can be in lead, brass, steel, aluminium or any other material, depending on the desired effects. In 20 gauge, the container and the pressure regulator are a single part. 

The container ensures the aerodynamic stability of the projectile and ensures its high precision at impact. It allows a subtle passage of all the chokes. Moreover, it avoids the barrel wear and leading. At impact, the bipartite inside projectile is released, letting the arrow and the hammer through. The inside chimney of the container guides the active projectile, thus reducing the ricochet. 

The shape of the central arrow favours : Target hooking, penetration in all shooting circumstances, deep penetration in hard zone, ricochet risk reduction. 

The hammer propels the central arrow and expands in soft zones. At impact, it amplifies the energy that it disseminates in the target. 

The pressure regulator ensures : a perfect gas tightness of the powder , a uniform thrust, a constant speed, a perfectly guided projectile.

This double effect is obtained thanks to the composition of the released inside projectile at impact. It works as a shock dart. The central arrow and the mass cause a high neutralizing power effect. Both parts with different materials act together or individually according to the resistance of the touched target.
