The advantage to a single stage press when considering something like this is that the single stage press requires the operator to put their hand on the case at each stage. If you use a written checklist, like I do, then you can include an inspection check at each of those operations.

My checklist has been refined over the last 39 years, but it currently has 22 operations. At the conclusion of each operation, a box is checked to indicate completion. It is slow, deliberate work, but I don't shoot that much.
