A particulate delivery and packing apparatus for depositing and compressing particulate material in elongate containers. The containers may have one closed end or two open ends. A modular elongate container magazine is positioned on a base plate of the apparatus to receive a controlled-descent hopper having a plurality of packing tubes extending downwardly from a bottom end of the hopper. Each of the plurality of packing tubes is aligned with a channel in the container magazine and is incrementally lowered into the channel to deposit particulate material. The leading edge of the packing tube compresses the deposited material via an oscillation movement and is incrementally withdrawn to deposit additional particulate material. A vibration-emitting electromagnet/magnetic conductor combination imparts vibration energy to the packing tubes to perform the packing/compression function. Alternatively, a motor applies rotational motion that is converted to a vertical vibratory motion imparted to the packing tubes to perform the packing/compression function.
