Progressive presses inherently have ONE differentiating principle of design which sets them apart from single stage or turret presses - automation. The goal of this automation can be twofold 1) increase production speed 2) reduce hand moving - which in itself typically influences overall cycle time, considerably.
We choose our battles here - it’s a balancing act of how much automation am I able to employ without compromising the quality of the ammunition. For example:
1) I abhor the wasted time of secondary tumbling to remove case lube - so I don’t. I use Hornady One Shot and only tumble once per firing. That significantly reduces my total cycle time.
2) I size and expand separately, which on a single stage press, this means an extra trip in and out of the press - which means more hand moving and would increase my cycle time. Using a turret press, I can cut my hand moving in half, which is OVERWHELMINGLY the greatest contributor to loading time at the bench. Using a progressive press with a case feeder & collator, I can daftly pull the ram handle virtually as fast as I want, rather than attentively placing the cases in and out of a single stage TWICE and pulling the handle twice as many times… A guy COULD prime on press, and even trim on press at that time too.
3) I choose to decap before cleaning, and choose to clean, so running a progressive press with a case feeder for the single function of decapping SLIGHTLY speeds up that step, but also significantly reduces my hand movement as labor investment - I just pull the arm, not load and unload the cases into and from the press. (Lee APP is great for this, in absence of a true progressive press).
4) Using a Giraud trimmer with an amp mate automated case handler and a case collator, trimming off of the press is automated, which SLIGHTLY reduces cycle time for that step, but significantly reduces (relatively eliminates) hand movement investment for that step.
So picking my battles to balance speed with precision, and reduce my overall labor input into the process: decap on an auto press with case feeder/collator, wet tumble, dry, One Shot Lube, Size and expand on progressive with feeder/collator, trim on power trimmer with case collator and automated case handler, prime, charge, seat, bang, repeat.
I REALLY would like to have an automated means of traying and boxing cases. I spend a lot of time in process just racking cases - I rack to spray after cleaning, to charge after priming, and to box after seating, so there’s 3 instances where I handle every case, one at a time, with requirement for precision hand movement, and I’d really, really like to automate those steps.
