Abstract (en)
[origin: EP0172549A2] The inventive device is composed of a device with a specifically shaped inner bore which is mounted on or integral with barrel (2) of a firearm so that the axis of the inner bore and the axis of the barrel are co-linear. The inner bore of the device is composed of two sections, seen in direction of propagation of the projectile: (a) a reverse taper (12) which appears to the powder gases as an abrupt expansion around the projectile followed by (b) a smooth bore section (13) whose diameter is equal to or less than the projectile diameter.
