Upgraded the Dillon 1050 to the RL1100, so far so good. Smooth buttery strokes, but a bit longer. Smooth indexing, overall a better press than the 1050. However, the 1050 and also the 1100 have both broken the primer assembly guide cam bolt. Dillon truly needs to improve or redesign the entire primer assembly mechanism. Had to send the tool head over to Dillon for warranty repairs due to having a broken un-removable cam bolt.
