  • Special flip-top system of closure (patented solution)
  • Cartridge case


  • Innovative method for loading hunting and shooting guns
    This technical solution for hunting and shooting gun cartridge manufacture concentrates in particular on the production of a new internal plastic disc, and consequently a new cartridge case loading method.

    The main advantages of this revolutionary invention may be summarised as follows: This case manufacturing method is based on an integral head and body design concept, which means that the high level of compression previously exerted by the internal plastic disc is no longer necessary. Simple, fast and more economical to manufacture, this new case has the following characteristics:

    It is solid and reliable;

    It optimises the structure of the internal plastic disc which comes into contact with the gunpowder, thereby maximising the ballistic effect;

    It acts as a shock absorber against the explosive force, thereby reducing the effects of recoil;

    It is simple and economical to produce.
