Abstract
A bullet cartridge (1) may include a bullet case (3) defining a caliber diameter (D), a projectile (4) inserted into the neck portion (31) of the bullet case (3), and at least one annular layer (51, 52) of a sealing medium (5) formed from a sealing medium (5) between the bullet case (3) and the projectile (4). The bullet case (3) may be provided with the annular layer (51, 52) using a microdosing device (microdoser) (7). The annular layer may include not more than 1 mg of sealing medium (5) per mm of caliber diameter (D).
Claims18
A bullet cartridge comprising:
- a bullet case defining a caliber diameter and having a neck portion;
- a projectile configured to be inserted into the neck portion of the bullet case;
- and
- at least one annular layer of a sealing medium formed from a sealing medium between the bullet case and the projectile and applied at a temperature of at least 25° C. and at most 60° C., wherein:
- the at least one annular layer is at least one microdosed annular layer, and/or
- the at least one annular layer comprises not more than 0.5 mg of sealing medium per mm of caliber diameter.
A method of manufacturing a bullet cartridge, comprising:
- providing a bullet case having a neck portion configured to receive a projectile, the neck portion defining an inner circumference,
- providing a bitumen-containing sealant mixture as a sealing medium, and
- applying, by microdosing at a temperature of at least 25° C. and at most 60° C., an annular layer of the sealing medium to the bullet case at an inner circumference in the neck portion of the bullet case.
An apparatus for manufacturing bullet cartridges, comprising:
- a holder configured to hold a bullet case having a neck portion configured to receive a projectile and defining an inner circumference;
- at least one heater and/or cooler;
- a temperature controller configured to control the at least one heater and/or cooler to provide a sealing medium at a temperature of at least 25° C. and at most 60° C.;
- and
- a microdoser configured to provide a predetermined amount of the sealing medium and apply the predetermined amount of the sealing medium to the inner circumference of the neck portion.
