摘要

The invention relates to a weapon for pulling a round of ammunition without outer carton and opalescent form of a projectile 6 provided with a powder charge 7, said weapon comprising at least one tube 2 having an open end 2a and a bottom 2b, and a fraction of the firing device 3 is adapted to cause the ignition of the powder charge by the intermediate means of priming 8. This weapon is characterized by the fact that the bottom is relates to means for temporarily retaining 9 cooperating with the projectile, these means being arranged to ceasing to be active, that the pressure developed in the bottom reaches a value p which can be optimized as a function of the calibre of the projectile, the weight of the projectile, the construction of the tube (a plain web and or a core rayee) and the nature of the firing is desired (firing at a short, medium or long reach), this optimization being made possible by a determination proper means for temporarily retaining.
