A method for manufacturing a housing enclosing a pyrotechnic charge and an installation for implementing this method includes inserting a pyrotechnic charge into a charging volume laterally delimited by a rigid cylindrical charging wall and into a lower part by a first element of the housing to be obtained; positioning a second element of the housing to be obtained of cylindrical shape above the inserted pyrotechnic charge and in the extension of the cylindrical charging wall. The second element has a lateral cylindrical wall of the same shape and diameter as the cylindrical charging wall and is able to cooperate with the first element, and jointly translating the second element and the cylindrical charging wall relative to the first element such as to make the second element cooperate with the first element and form the housing enclosing the pyrotechnic charge.

An apparatus for removing spent primers from spent ammunition shell casings includes a body having a shell casing feed channel defining a punch zone and a shell casing feed zone, a guide channel and a shell casing inlet channel intersecting the shell casing feed channel at the shell casing feed zone, a shell casing feed plunger movable axially along the shell casing feed channel from a first position adjacent to the shell casing feed zone to a second position in which the shell casing is moved within the punch zone for removal of the spent primer, a handle assembly movable to drive the shell casing feed plunger from the first position to the second position, and a plunger guide assembly having a length adjustable to correspondingly adjust the travel distance between the first and second positions of the shell casing feed plunger.

A shaped charge liner may include a plurality of liner segments for a shaped charge configured to perforate a sidewall of a wellbore upon detonation. The plurality of liner segments may include a tip liner segment comprising a first group of compacted metal powder having a hollow cone shape with a trailing interface end disposed opposite a tip end. The tip liner segment is configured to be disposed in a shaped charge casing of the shaped charge. The plurality of liner segments may also include a base liner segment comprising a second group of compacted metal powder having a truncated hollow cone shape with a trailing base end disposed opposite a leading base interface end. The trailing base end has a larger diameter than the leading base interface end, and the base liner segment is configured to be disposed at least partially within the shaped charge casing.

Disclosed are processes for loading a cartridge such as a shot shell with a shot load and a charge of buffer material. The processes employ a tube that is coaxially aligned with the axis of the cartridge case or shot cup, the tube having an outer diameter that closely fits into the inner diameter of the cartridge case or shot cup. Shot and buffer material are loaded, the leading edge of the tube is inserted to a sufficient depth to cause at least a portion of the shot load and buffer material to rise into the inner volume of the tube, and the tube removed. The insertion-removal cycle effects the efficient mixing of the shot and the buffer material and can be repeated as many times as desired.
