ABSTRACT:
A safety filler for underloaded firearm cartridges, in which the volume of powder is less than the volumetric capacity of the powder chamber. The filler comprises a sleeve that is inserted into the powder chamber, which radially reduces the typical interior volume of a cartridge shell so that a lesser amount of powder charge fills the remaining space to about 90% of its available capacity. Being preferably made of a flexible and resilient material, the filler sleeve can be inserted into a cartridge shell having a necked-down configuration. The specific configuration of the filler sleeve provides for a reduced volume powder chamber within the cartridge to allow an even distribution of the powder which will burn evenly and uniformly, allowing safe firing of the bullet.
