Disclosed is a device for sensing the powder level within a cartridge shell during the reloading process comprising a housing having a ramp in its interior, a sleeve slidably inserted within the housing having a radial hole initially positioned below the ramp in which resides a ball, and a plunger inserted within the sleeve having a groove for receipt of the ball. A probe is mounted on the lower end of the plunger which contacts the powder deposited in the cartridge shell, wherein the probe lifts the plunger so that the groove in the plunger may receive the ball upon the presence of a proper amount of powder so the sleeve can slide upward into the housing allowing the cartridge to enter the housing. Preferably, the powder level sensing device is adapted to be mounted onto existing reloading press frames, particularly the progressive reloading press frame. Also disclosed is a method for adjusting the powder level sensing device to accommodate various cartridge shells and desired powder levels.

An apparatus for detecting the presence of an insufficient or excessive amount of powder deposited in a cartridge shell and for preventing that improperly loaded cartridge shell from completing the loading process so that any defective condition can be corrected before a safety hazard results from that defectively loaded cartridge shell, comprising: a housing adaptable to be mounted on a press frame having upper and lower sections where said upper section has an interior cross-sectional area less than the interior cross-sectional area at said lower section and having a downwardly facing sloping ramp on its interior surface at the change of the two cross-sectional areas; a sleeve slidably inserted within said housing having a hole extending radially which is at least partially below the ramp when said sleeve is in its initial position; a plunger slidably inserted within said sleeve having a groove thereabout; a probe mounted on the lower end of said plunger; and a ball within said radial hole having a diameter so that it protrudes beyond the exterior surface of said sleeve when against said plunger and when said sleeve is in its initial position, and when said probe and sleeve are in proper relative positions with respect to each other upon the presence of a properly powder-filled cartridge shell, the ramp will force said ball toward the groove of said plunger so that said sleeve can move upward with said probe and plunger as the cartridge shell contacts and forces upwardly said sleeve, and when said probe and sleeve are not in proper relative positions, said ball cannot move toward the groove and thus is positioned against said ramp so that the sleeve remains in its initial position, thus preventing the entrance of the cartridge shell into said housing.
