Abstract
As described above, this new primer feed system is both accurate and consistent. The primer feed station begins by loading primers from the vendor packaging into the vibratory feed bowl via the primer chute. The bowl has an adjustable height polycarbonate guard that is inside the main safety polycarbonate doors and exits above the machine. The bowl then orients the primers open side up and discharges them into the primer track. Crimping can be done with 3 or pins or a complete radial crimp. Previous versions of the crimp station on these crimping machines involved a pin mounted to the upper ram and a lower pin actuated by the lower ram. It was difficult to time and adjust properly for a consistent crimp. This new approach to crimping has proved much more reliable, accurate and easier to adjust. It still utilizes an upper pin mounted to the upper moving ram assembly but the lower pin is fixed.

Abstract
Herein described is a small caliber ammunition production loading machine with a novel measuring location and device. The machine will load one cartridge at a time and is referred to as a ‘single-out” machine (see FIG. 1). The machine will be similar in nature to existing loading machines with the following key novel aspects: a) The cartridge overall length (OAL) will be measured both as an overall dimension which is industry standard and also at a key datum location on a bullet's ogive. Measuring to a repeatable datum point on the bullet's ogive gives a more accurate representation of the cartridge's ballistic ability.

Abstract
Described is an ammunition production loading machine. The machine will load two cartridges at once and is referred to as a ‘two-out” machine. The machine will be of a mechanical nature reducing the potential loss of production that occurs with pneumatic systems. Any pneumatic systems on the machine will operate only in failure instances, i.e. in the case of a powder failure the pneumatic system will obstruct the projectile feed mechanism. The machine consists of seven (7) major components, which operate in unison. The machine is intended to run a single caliber so changeover adjustments and time required to change calibers are eliminated. The machine is capable of precisely loading a complete cartridge at a rate of 240 parts per minute in a completely automated manner. The key features of this novel machine are the full automation from station to station and a cartridge retaining bullet crimp case bushing in a rotating main disk, which rotates cases from station to station. The bullet crimp case bushing has a tapered feature inside which crimps the case to the bullet. Machines in the prior art utilize slotted case inserts or features to hold the cartridge base in position for loading, which relies on a separate tool for crimping and are not fully automated. The herein described machine is fully automated and does not require a person to manually move parts from one station to the next, nor loading of individual inserts to effectuate the bullet to case connection.

Abstract
The herein described Table Top Priming Machine for Small Caliber Ammunition provides a simple, safe, and more precise means to produce reliable ammunition than other priming machines in the prior art. The Table Top Priming Machine uses a unique rotary disk assembly to hold cases as the machine installs primers into the cases. Gravity assists with securing cases in the disk assembly and promotes ejection of the finished cases. The compact construction of the machine makes the machine accessible for individuals or manufactures with limited space to create consistent ammunition at high speeds with limited space. Furthermore, the machine's design allows for any end user to assemble and maintain the machine with general hand tools, which obviates the need for specialized maintenance from the manufacturer.
