A loading machine includes a drum cam configured to rotate and having a cam path. A first track is positioned proximate the drum cam. A rammer subassembly is engaged with the drum cam and the first track. The rammer subassembly is configured to move between an extended position and a retracted position as the drum cam rotates. The rammer subassembly has a first rammer section engaged with the cam path and configured to move longitudinally during rotation of the drum cam. The first rammer section includes a first gear engaged with the first track such that longitudinal movement of the first rammer section causes rotation of the first gear. A second rammer section is telescopically coupled with the first rammer section and is engaged with the first gear such that rotation of the first gear causes the second rammer section to telescopically move with respect to the first rammer section.
